I am running a set on my pump gas 394. They flow 337 @ .650. Motor made 662 hp at 7200 and 533 tq @ 5400. I still have not sorted it out. I only shift at 6800 and I don't have the timing turned up where it supposed to be (I am scared of the junk pump gas). And I built the headers which was the only set I have ever built.
