Will 340 HP manifolds fit 360 crate engine?

Wow, that's a big diff in exaust loss on the headers vs manifolds.

Might have to decide if the ease of mantiance/ stock look will be worth the hp loss.

Thanks again for the info there.

YOU CAN NOT GO BY MY LOSS!!!!!!!!!!


What I said is that the loss/gain will depend on the build.

My build was all high RPM (8000rpm shift point) so I lost a bunch because the manifolds would not flow there.

The posted link above comes up all the time…… It is also useless unless you are building a 300hp, 360 (or similar engine).
