537ci Really Sic Pak Wedge with Trick Flow Heads

[Canyon707]

I wonder how good those heads are compared to performer, and others. I wonder what that elusive combo is... I run performer with an M1 intake and a 1050dom. what gears do you have in your diff??

From my experience, these heads are as good as the CNC ported Performer Heads with an even better chamber and a boatload more room for a taller valve spring. I built this engine for someone else but his car has 4:10 gears and is essentially a gutted A body.

Here is a dyno competition from Mopar Muscle Magazine where all competitors were required to use RPM cylinder heads. Rules were, hp/$ was the winner, but #3 finisher (we has met them and they is us) did pretty good hp/ci with our ported RPM heads.

Eventually the 451 using the same RPM heads made 787 HP at subsequent dyno tests with 91 octane.

Another friend of mine went for a ride today. When the outboards come in at highway speeds, it blacktracks the road. I bet it's loads of fun!

6 packs were rated at 390hp

Babbahahahaa sorry , I had to.

Yeah they were - but that was before the engine was built. I'll be bet with the right combo you'll get a heck of a lot more than that out of a six pack set up. I got 555 hp out of mine and that was with out really trying too hard.

Jim (IQ52) got 590 out of mine, with 440 cu in

Yep, and I believe him when he says it'd go 650-700 with just a cam and intake/carb swap.

We were contemplating that on this one but we didn't have the luxury. We could have tuned in another 10-20hp just with an oil change. This one held 80psi all through the pulls.
