I just wanted to know how many 331's were out there using 24lb injectors and what fuel pressure you guys are at?? I have a 325 just a bit smaller and have it set at 46 and running a little rich and was planning on trying to turn it back down to stock 39psi??

go buy a wideband and do some tuning yourself ......best 350 dollars I ever spent was buying a wideband ......once you get your air/fuel dialed in , add timing till it pings and then back it down a few degrees from there and you will be surprised at how much faster it runs ...

With the Cobra intake I would bet that your power is done by 5600rpm even with the stroker, and the cam is dead by then as well.... I would think in the upper rpm range you may need some more fuel so 42-44psi.

Best is to read a plug and go from there....

With your mods I would guess around 370-400 HP, 50psi on 24#ers will support right at 400HP, so I would leave your pressure alone and adjust the TPS for any part throttle tuning. It would be best to get a part throttle dyno tune.

Yeah Rick I was not planning on turning more than 6000rpms with this set-up. I am going to get it tuned in a little while anyway but just was wondering where other's with a 331 and 24's are at.
