Re: '65 GMC 1500 project. From the Netherlands
I don't have one at this time - but I have see/heard my truck on video - I think someone on this site may have it. They commented that it sure didn't sound like a V-6. Next time 1 of my computer savvy buddies with a smart phone stops I will post a video.:thumbsup:

Re: '65 GMC 1500 project. From the Netherlands
Asked a local company that specializes in spray welding for repair work to build up the camshaft by spray welding. They advise against it due to the poor bonding to hardened surfaces, and the risk of the new surface flaking off.
Too much work and trouble for added lift. Might make custom 1.6 rockers in the future, we'll see. I've sent the camshaft to the cam grinder today together with my specs. Also took a look at the valve lifters - measured the face surface with a dial indicator by sweeping the lifter on a flat surface. The originals are cupped in (concave) from the wear. They should have a crown. (convex) I also bought new Melling lifters to test, they have a flat face :banghead: But, I also measured hardness with a Vickers tester of the lifter faces. I wanted to check the new Melling lifters vs the OEM lifters for hardness. I tested 2 of each lifter: OEM lifters: No. 1: 629 HV (56 hRC) No. 2: 690 HV (58 hRC) Melling lifters: No. 1: 750 HV (60.5 hRC) No. 2: 748 HV (60.5 hRC) Interesting results. I figured the Melling lifters were much softer, low-quality pieces. Properly refaced, they should last a long time. Now to reface the lifters. Since no one refaces lifters anymore in the Netherlands, I'm going to think up something myself... |

Here is the quickest way to pull the camshaft without removing the radiator support - just loosen the front engine mounts and use a jack to tilt the engine.

Placing a crown on them would reduce the spinning effects. On a side note, roller lifters camshafts does not have a ramp on the lobes. You do not want those lifters to rotate. |

This is what is needed for lifter regrinding.

If you need lifters resurfaced, I deal with a well known cam grinder in my home town here called Delta Cams. I'm thinking it was $100 to resurface the 12 lifters. I have an extra set of these if you get into a pinch I send in to get resurfaced then sent to you.

They have been grinding my cams since back in the early 80's. When I was racing they built me a couple custom turbo cams for my 351 Windsor motor and I flew. Lots of experience there and they gotten a lot of people needs straightened out.
