Just figure I'd give my opinion even though I think I'm out numbered. I ran 40 Series Flowmasters on a 340 small block .60 over with 360 J heads 2.02/1.60 3 angle valve job, .528 solid lift cam, Harland Sharp 1.6 ratio rockers.

40 series flowmasters with Hooker competition headers, 2.5" with x-pipe.

I love the sound of a small block that screams and I'm more into loud cars. The thing I loved most about the car was when you would gradually press down on the gas and the cam would hit it's power band because it sounded like the car was turning into a monster.

I have a buddy with a 440 that is built up pretty good. Just updated to a 440 source cam and head package. He ran Hooker headers 3" pipe with x-pipe and 40 series flowmasters. I will be honest I don't like the way it sound on a big block for some reason.


Anyone run the super 40's or super 44's?

Had Summit race headers 2.5" pipe with x-pipe and super 44's on my 88 power wagon. It was only a 318 so it's hard to get any sound out of it.
