350 rebuild for 87 blazer

[BLAZERnewb]

I figured since rebuilding my 350 is becoming a project all it's own, I would start a new thread. Began gathering new parts for the rebuild today. I'm (for now) just rebuilding my 350 stock. Went to autozone to get new rings, rod bearings and main bearings. I got the rings. Get this, autozone didnt carry stock 350 rod bearings (have to special order them). And turns out my rear main bearing was a different size than the rest... Has anyone ever heard of such a thing?

[spacecadet]

Yup. I had 3 differnet size main bearings in my crate motor.

wow... how did u get bearings for it?

[ZR1BLAZER]

flip the bearings upside down. it will give the size. std, .010, .020, .030 if the crank has ever been turned.

cleaning my old pistons today... plan on reusing them...
cut the hell out of my thumb with one of the old rings... thats means they're bad right?

if you have it apart i would replace them regardless, how do your cylinders look? you might want to hone them at a minimum if your not sending it to a shop.

here is a little web page explaining the cheap way to do it, of course this will not produce the same results as a pro shop!
