Anyone have a simulator to estimate the approximate flywheel HP/Tq this combo would make with the L76 EFI intake versus the GMPP Carb?

6.0, 11 to 1, 228/236 588/592 cam, PRC CNC L92's w/650 springs and Ti retainers, LT's, LS7 lifters.

After reading some flow numbers on the L76 intake I am wondering if I would be leaving some HP on the table by not going with the carb option....but I would love to have EFI.

 

do a carb style intake with EFI. Probably don't have big enough engine to waste the time on it though. Get up to 427+ cubic inches first.

You should make about 450-470 RWHP with the stuff you listed.

 

You will lose power with the carb intake gm hi tech performance did a test and on stock displacement engines you will lose alot going with the carb style intake. It only seems to limit strokers. I also agree with 450-470rwhp.

 

Thanks Guys. EFI it is!
