Re: More HP idea's
Agree with most here - heads.
Since a 327 CID and short stroke, meaning low torque, you're going to have to build for torque - the effect used to peg the 'Seat-O-Pants' meter.
Don't go overboard on heads, stay small volume for keeping the intake charge suspended and fast velocity, and exhaust should be 70%-75% of intake by volume, paint Chebbie orange for the sleeper look. 1.94" intake diameter work well. Small chamber and steel shim head gaskets - be sure to 'hone' the deck and the heads for a good seal - use a new Norton India stone for honing and lube it to keep it clean. Better to remove dowel pins & emery paper the pins for a slip fit.
A good aftermarket dual plane alum manifold, again, paint Chebbie orange for sleeper look.
Take a set of exhaust manifolds and have them extrude-O-honed to increase the ID.
Change to 2.25 dual exhaust with X.
Now you will have a nice sleeper.
Good luck with your build.
