383 ideas

Hello gang, I came across a bare 350 block this weekend (3970014) and I am looking into a 383 build. I have a pretty stout 332 (327) now that I am happy with, but I want more. This 350 came with 882 heads (will not be using) and the crank, but no main caps . So, I guess I am asking what I have to do to bet theis 350 ready to build since it has no caps. Is it true that is has to be align bored to fit a new Scat 383 crank? I already know that a new set of pistons are needed, but what else from the 332 can be used on the 350 block. Does the 383 require different rods? I would like to swap and re-use all that I can, intake, cam/lifters, double roller, carb, ect. The heads I have now are a set of fresh 64cc 2.02/1.60 (3947041 cast) with 3 angle job with springs matched to the Comp 280h cam. Please give me some feedback on this. Thanks guys.

If you ain't got the main caps , you don't have much, for what it would cost putting new caps and alilgn boring , you can find another block.

DITTO: That 350 block is worth the going rate for dirty cast iron.

You are looking at a couple of hundred bucks just to get it crank worthy. Line bore/hone with mismatched caps is pricey!!

You can use either 5.7" or 5.565" rods. Match your piston purchase to the rods. If your 327 rods are 2.100" journal rods you can use them. If 2.000", no, unless you cut the rod journals on the Scat crank down to 2.000". Don't re-use the old lifters in a different block. Use new lifters.

Interference is usually found at the shoulder of the rod at the bolt head where it interferes with some of the cam lobes. You can grind the offending rods or purchase a small diameter lobe cam that will clear without grinding. If you do that, you'll need longer pushrods. The alternative would be to use the 400 rods (5.565") that will most likely clear everything.

The block will probably need some clearancing at the pan rail with 5.7" rods.
