Hello I am a new guy, 21 years old and realy into Buicks. I drive a 76 Century and I spun a bearing in the original Buick 350@90,000 miles. I picked up a 80 Buick 350 but I am wondering if parts will interchange between them??
The '76 and '80 motors should be identical. If the '80 is a good runner, I would just drop that one in the car instead of swapping parts to fix the '76 motor. I have seen a spun rod bearing on a Buick 350 before, but it was a neglected, beat motor with 150k on the clock. I rebuilt the 350 I used to have in my skylark back in '99, it had 212,000 miles on it and the bearings still looked good. I would not say that a spun bearing at 90k is typical of a well maintained engine.
I found them in the link of my sig. Possiable that its a tad wrong but even the other makes come out right or have the right info posted from what I know. and only the top section seams revelant to stock, the rest I don't know. but so far the top stock specs seam right for all 3 brands I own. And the other I have owned.
Thanks for the info. The 80 motor runs good, has only 80,000 miles and will be temporary. I took off the intake manifold, valve covers, and oil pan it is very clean just a little carbon. I also got the matching th350 so I will get a shift kit put into that for when I get a older done up buick 350 motor. which year block is the best 68 or 69???
I think all the 350 blocks are pretty much designed with the same amount of strength. Anyways, you'd have to be running some serious power to have problems with the block holding up, they were engineered very well.
Thanks thats good to know, maybe I will hot rod my 80 350 and rebuild the 76 350 to stock. I only want to race once a year so I can just switch motors and go to the track!
