305a V6 ignition parts
Where do I find them?
I want a new: - cap ( believe its a screw down type, not the 1/2 or 1/4 turn latching kind ) - rotor - condenser - coil - wire set I found some parts here, but I'm not sure of the cap since they don't show the underside. If someone has bought these before and still has their order history and manufactorurer & part numbers, that would be super helpful. Thanks, Scott |
Re: 305a V6 ignition parts
Scott, you need to learn how to use the internet for parts more effectively. If you can't find them, we can help. But you need to try first. I found everything you want at the first place I tried , Rockauto. This is not to discourage you from posting a problem or question. Trying to inform you that all we do is look it up for you. Try O'Reilly's, Autozone, Napa, etc. or whatever you have in your town if you don't want to order online from Rockauto or your link. Usually if you have searched correctly and they say it fits, it most likely fits. Buying locally is always better to check the part at the counter and for returning. But I buy a lot from the internet because of price and not available locally.
P.S. I have the same truck you have....cool! |

I owned a 61' chevrolet truck with a more conventional v8 and parts for that were super easy to find. I've ordered many ignition parts from Rock Auto that have turned out to not be correct for my truck. I'm asking these questions here because all the other avenues have failed to yield the correct parts for this non-typical engine. I have looked at other sites and they list parts for only the I-6 engines. Please don't assume someone is Internet inept or hasn't already attempted other avenues when they most likely have. The most likely case is, perhaps the distributor for my truck was switched out and is no longer oem and this is causing me to not find a match on all of the online resources. Thanks for the 'advice'. |
Re: 305a V6 ignition parts
Another quick search on O'Reillys website shows every part you need for 1960 GMC 1000 series 305 V6. But you say you have ****"tried" them. I recommended you go to a place like that so as to be sure it fits and returns are "no questions asked." There are 14 O'Reilly's in Austin. If you have an odd ball Dizzy, you will have to identify it before anyone can help you. But I doubt you do. You are welcome for the advice. I like to help those who are trying to help themselves.
Some parts for these motors are hard to find, some are not. ****("Please don't assume someone is Internet inept or hasn't already attempted other avenues when they most likely have.") So go get your parts and get it running down the road. |
Re: 305a V6 ignition parts
On the subject of Odd Ball dizzys...did anyone else ever have the dizzy with the dual vacuum port advance pump? My new one has a single hose, but my old one had two hoses coming from the pump.

Re: 305a V6 ignition parts
The thing I like about the various forums I visit, including this one, is the tradition of almost unfailing courtesy and helpfulness.
I don't read every post so there may be some "history" between Pirate and Ken that I have missed. If not, then the courtesy I expect seemed a little strained here. I hope it is a one-off. |
Re: 305a V6 ignition parts
If you want to look up stuff for people who don't even try themselves, then they bite the hand that feeds them, why don't you look it up and help? instead of bashing on here. Your comment can only add to whatever "straining" is present. All my comments are full of genuine help in them, including a tip for a person on his very first post here. (That should have told you there is no history.) This issue had settled until you posted. The courtesy starts with not treating a forum as your secretary. "Hey look this stuff up for me guys while I go bowling".

Re: 305a V6 ignition parts
Ed, after you posted I did some checking. Didn't know about smaller/larger dizzy. If vendors info is correct, I found that 60 and 63 use same cap but there are two choices for rotors, slip on pointer type and the two screw disc kind.

Re: 305a V6 ignition parts
Here is some info from a GMC enthusiast and expert:
GMC v6 engines came with one of 3 different dizzies. First the externally adjusted style. Just like the 230-250-292 stuff. It has the spring arms to hold on the cap. Next is the internal adjusted style. More or less the same as the later 235-261 Chevy and jimmy 248-270 302. Screw on cap. Third is the externally adjusted dizzy with the governor control. This has 2 vacuum ports and is taller under the cap. These came on 1-1/2 ton and larger. There seems to be no rhyme or reason for use of the first two styles. Though the externally adjusted caps seem a bit more common. Both styles have appeared on all series of 305 engines. |
Re: 305a V6 ignition parts
Actually the 230-250-292 had screws to hold the cap down and were internally adjusted. The older 216-235-261 had the externally adjusted dizzys and the snap on straps to hold the cap down. Nice to know what truck my 305 was out of. It had that governed dizzy.

Re: 305a V6 ignition parts
My 1963 Chevrolet Truck Shop Manual shows 6 cyl 230, 292 Distributor cap as spring loaded retention and external/window adjustment as previously posted.
My 305A and 305E have the exact same Dizzy/cap/rotor/etc. Spring loaded cap, external adjust. |

I guess I took the response the wrong way and I apologize to Ken. I always search the forum for the answer before posting my own thread. I just didn't see anyone else having an issue with finding correct parts is all. I am always very gracious for any help, but I guess I have a hot button when it comes to any (my) perceived condescending comments. Apologies for the misunderstanding |

Next time I'm at my truck I'll pull the ignition parts and post them, for future reference. I'll dig into the information above. Thanks again. |
Re: 305a V6 ignition parts
When I was getting parts for my 62 with a 305 D motor I used the Napa on line site to do my parts research. After I selected my year truck on the site I could then select my local store. Then I could peruse inventory and see what was in stock. Everything I needed for the dizzy was in stock, worked correctly. What really took me back a bit was how expensive the externally adjusted points and matching cap were. But from experience, Napa has top quality ignition parts so I got the best for my baby.

Re: 305a V6 ignition parts
I do a lot of "shopping" on line to get part numbers and pictures, and after many corroborating facts, I then try to find the parts locally so as to touch and feel and compare before buying. Just as Jagarra said. I have found that some online retailers are easy and fair regarding returns. I don't use any of them unless I have to or the price is way low. Amazon seems good for returns. RockAuto is NOT. I don't use them anymore for purchase but really, really, good for part numbers. As I said way back, buy at a store near if you can. I have learned to do cross referencing on the internet. It has taken a lot of time to learn how to do that to end up with the part at O'Reilly's. They do not always have an old truck part listed on their site or computer. Their dates don't go that far back sometimes. I am speaking of all kinds of old trucks/cars I have worked on, not just GMC. Places like O'Reilly's will take back a part, no questions asked especially if you have built up a rapport.

Re: 305a V6 ignition parts
Points adjust thru "window" built into dizzy. Dwell. How could you interpret turning dizzy as internal/external adjustment?
Anyway sounds like OP is on track. |

Just to follow up here, so it's helpful to others in the future and they don't think they are going insane, I ran into discrepancies between what the major auto parts dealers offer and what is on my truck.
The distributor body has 'Delco-Remy 1110317 6E10' stamped on it. That hasn't found me a cap yet, but I'm going to keep digging. The picture below comparing the caps, the one on the right is the original (to my truck). You can see that they are very different in size and fastening mechanism. The points seems to wrong as well. I'm posting the original points I pulled. If anyone has any pointers, it will be greatly appreciated, but I'm going to keep digging. Thanks! Scott |

http://6066gmcclub.com/forum/archive...p/t-48166.html Indicates that the distributor is probably stock since it is on another member's v6. If I get time I'll look around and see what distributor cap/rotor that the "kid" got for his (was mine) truck. He works all day and pretty much passes out when he gets home so asking him isn't an option. :) |

Basically, I chased down the distributor part number on rock auto and it pointed to a distributor for a 1964 GMC 1000, but none of the caps matched the distributor (distributor had holes for screw down style cap and the caps shown for the 1964 were the type that have the arm that slides under a lip on the distributor body (wrong) ).
I dug a little further and found a distributor contact (points) that matched mine on rock auto, so I search amazon for the points part number, and low and behold, the amazon 'commonly bought together' section showed a cap that 'looks' similar to mine. I'm still doing research on this, but it looks promising. It is nice to see that petronix or at least in this post they identify a larger and smaller distributor cap and one with a window (larger) and one without (smaller). Mine certainly doesn't have a window and is the smaller of the 2; so at least that lines up. |
Re: 305a V6 ignition parts
Appears you have the later model small cap distributor which shares the same cap with Chevrolet 230. 250 and 292 inline six engines up to 1974, there shouldn't be problem finding this cap.
|
Re: 305a V6 ignition parts
Good work Pirate, that's how you do it. Search and research. DON"T buy online for hard to figure out parts, especially RockAuto, they will NOT give money back because of the way you buy from them, it locks you in.
|
Re: 305a V6 ignition parts
May or May not work, looks like it. The key is you can order it into store, go there with your old dizzy and see. All for free.

Re: 305a V6 ignition parts
You can get a 292 cap for cheap at Napa. That's what I used on my 305E's old dizzy was a spare 292 cap I had laying around. Good work!

Re: 305a V6 ignition parts
Buying on line is not the same as what I'm speaking of at O'Reilly's. They either have it in stock or get it same day at the store. No shipping cost, real fast. I find it on their website, as I did for you, call them and see if it is in stock, if not they order it for afternoon delivery. Once in a while it takes a day or two if it's in out of state warehouse.
The bottom line is: Is the cap I found what you are looking for? As of Monday 24 Aug, It sounded like you still did not have one, were getting ready to order the Amazon or were still researching. Your response seems to indicate you think I'm pushing a certain store, I am not pushing any particular store, just finding the cap you need. Seems pretty easy to go look at the one I posted? You did not even acknowledge seeing the cap I posted, just talked about NAPA. The Amazon, Delco U305 is the same cap as I posted on Monday 24 Aug., at O'Reilly's. |

I was merely just adding that the parts I had previously ordered (that didn't fit, that were in the pictures) were from Napa online and they refunded everything except the shipping. Just adding to the conversation. I will acknowledge and confirm your oreilllys findings when I get a chance to physically get to the store. |
Re: 305a V6 ignition parts
O'Reilly's has the Delco U305 in the same group as the Master Pro 2-4211 (my post). It was listed as not available. The rotor used with this cap is Delco U403, also listed as not available.
This is the rotor in that group that is available. http://www.oreillyauto.com/site/c/de...+cap+%26+rotor And Delco U110 was in this group (not available) but this is: http://www.oreillyauto.com/site/c/de...%26+condensers |
Re: 305a V6 ignition parts
I was checking my old Motor's manual to see what distributor number was called out for this truck. Seems the number for a distributor for a 1960 305A is 1110248. further checking showed that the number in question doesn't appear anywhere, but my list only goes to 1964. So no telling when this number appeared.
After I did some more checking by Goggling that distributor number, it comes up as one for industrial and tractor applications, that may be part of the problem of why there is so much difficulty in finding parts that fit. |
Re: 305a V6 ignition parts
I was thinking that going by distributor number is IFY. My 1960 305A stock motor and my stock 305E have the same, larger diameter cap with twist lock. So many times PO's may change something, the best thing is to go where you can touch and feel and compare. As you say, old numbers are hard cross ref at auto parts stores. These parts I found are for 67 Chevy K15. Pirate came up with the same part number that I did using a different search technique. I think it's a done deal. I got my clue from the outside GMC Guru info I posted.

Re: 305a V6 ignition parts
Actually in later years, 66-74 the small cap with no window was the most common, the window style cap on these engines in later years was non existent.
