Re: Freshening up a 351
 

Thanks Bill!

This weekend I finished tearing down the short block and completed blasting/cleaning all of the parts for the 351. Unfortunately, I think #3 rod bearing spun. So, that means the short block is going to a machine shop to have the crank turned. I didn't get a chance to measure all of the cylinders to see if they are out of tolerance, but I guess I'll have the shop do that as well. The good news is that the crank had all standard sized bearings meaning that it can be turned no problem. So, it will be awhile before I send it out because over the next two months I need to purchase all the window seals and rubber for my 'burb so I can finish that project before spring.

I also decided that I am going to run TBI on this engine when it goes back together. I drew up this schematic for an adapter that I am going to make:

What do you guys think?

After installing a Howell TBI on a Jeep 304 V8 I contacted Howell if it would work on my 478M V6, they said it would work. Since it's based on GM TBI makes it a proven system and relatively simple installation and reasonably priced. That will be a great upgrade for any GMC V6.

That's encouraging! Do you have any links or more info? What kind of price range am I looking at?

Re: Freshening up a 351
 

The price is in the $1200 range and other GM TBI based systems.I don't have Howell's contact information at this time, just go online and you'll find it.

If you can get a TBI system woring on the GMC Big Block V6, that would ba a geart inprovement, keep good notes and lots of photos, then send me a write for the website like you did on tha Dual Carb setup.

Any up dates

Re: Freshening up a 351
 

No updates at this point gents. After tearing down the short block, I found some semi-serious scoring on the cylinder walls and cam bearings that need to be replaced. You all know how difficult it is to find a set of piston rings for this engine so I kind of lost steam on it. I keep checking ebay every now and then but not too often. So many other projects right now.

So, for now, she is on the back burner until further notice! Thanks!

I wonder if you can have them made somewhere? If so, what would it run?
