Anyone have exper with using Alum flywheels on 5.0? I just put a Alum FW, New clutch and Alum D/S. It feels like I've lost 1/2 my power.... I understand the rotating mass concept, but It seems to me the car should at least accelerate hard, then drop off between shifts, but this thing is dead across all gears and RPM ranges.

One note-- I did also replace the stock exhaust with a set of BBK equal headers and a BBK off Xpipe- The X pipe doesn't reach the flowmaster muffler pipe on one side I have to get a shop to modify.. So maybe the lack of backpressure???? One side of the X is bolted up the other isn't.. The power loss is so drastic, doesn't make sense to me


Please send help.. This is the project from hell (Theres more weired stuff for later) :sosad:
