They say you have to use offset inlet/center outlet mufflers to make the Flowmaster tailpipes work.

And By the way Ernie's motor has a max of 10.25:1 but im sure its acually 10.07:1 just needs to know how far down the pistons are in the hole!
He can see what it is whenever he freshens it up, Not bad for an engine that is not even zero decked lol!

No but have done some backroad testing with the new carb body...hard to tell if there is a power increase...within a couple weeks be back at the track...

So TA Man, you prove that the KRE 290 heads are providing good enough performance so that you may not have much to gain if at all by getting your heads ported to 305 or so.

Odds are high it would run faster with a little more head.

I had a good discussion last time at the dragstrip about headflow...Another fellow Pontiac racer insisted more head flow is always good...I disagreed it is not always better..all depends on the combination...

Yep, look at original Ram Air V heads.

More CFM is far from always better!

Velocity is an extremely important consideration.
Agree about balancing factors in the combination.

[ponjohn]

More cfm may not be beneficial if the cam is too small for the head flow.

I'm going to try and do it the hard way first!In decent air it would have went 11.1's..thats getting pretty close...and I've never expected to run 121/122...just the matter of getting to the track more..the 60's will come down a bit thinking 1.60's,still not leaving as clean and hard as it can.,testing this annular main body next..I have a small list of things to do this year..hopefully everything can get tested.

Has anyone tested this combo with a well adjusted q-jet?
If so what intake?

And, Ernie what size headers?

Andy (Torquewar) has a similar combo with a RPM and a Q-Jet. His last post here was post #195, there are several before that. All good reading!

[Torquewar]

I have been running a Q Jet and a self ported RPM.
My best MPH is 122.3 with a 11:44 and spinning for 3-4 ft limited traction.
Car has always ran flawless on the street and track.
Have a T-2 and a Shaker(Jeff)) 455 4150 to bolt on very shortly.
Im also trying to get the 60ft s down but im eager to see what the intake combo will do.
