Getting power out of a 63 /6?

I see, You ar talking about the junk after market cold air systems they have out on the market :coffee2:
Did not mean to come off as arguing Dan, I just voiced an opinion on colder air verses air in the engine bay area, and running a bigger filter for less restriction and still get filtered air. :coffee2: no disrespect intended Dan.
You have helped me allot and I am glad you spend time here and share your knowledge :cheers:

With an eye toward performance, with SOME MPG benefits thrown in, here would be my recipe for a fun car:

230/230 cam @ .050" lift, .445" total lift
390 4bbl carb
headers into duals, 2.25" tailpipe,glasspacks
.100" off the head for a 9:1 compression

This combination should give you a high 15 second car, that will still get 20 mpg on the road.

Just my 2-cents... and probably overpriced at that....
