Currently finishing up my 440 build. I want to reuse my factory hi-po manifolds from my roadrunner.

The two cams I'm looking at are the Lunati 60303 and 60304.

I've read on other posts here that guys ran the 60303 in low compression 440's but had headers. I want to run the 60304 since my 440 short block is running six pack pistons and higher compression.

Can I run the larger cam with hipo-manifolds and a 3 inch exhaust or is it not a good idea?
