Thread: Small block to Big Block

Tweet

I have a fiberglass 32, fenderless Coupe with a 350 in it now. What all would need to be done to change over to a big block? I assume the driveshaft would have to be shortened?

The engine mounts and tranny from the small block would all still be the same. RIght?

Thanks,

It's pretty much a direct drop in, just may need to redo your exhaust connections to the headers. The trans will stay in the same location, no need to change the driveshaft. Motor mount location will stay the same.

Caution, once you go to a big block you will not want to go back to a small block again.

well yes it is very true its very hard to stop at just 454.. well for me anyways looks like my 735 cid is moving a head

You should have no trouble with your used car. You might need a car radeator, also ex-system or headers are a lot better and the rest of the parts should fit no problem
