Congrats on the CE ... they all are a blast to drive. :Rowdy
I agree with lt4man ... my CE LT4 dynoed at 308 RWHP / 314 RWTQ using the 15% generally associated with manual drivetrain loss thats 354 HP / 361 TQ at the flywheel. This is on a "stock" LT4 ... only mod was muffler elims. I've done quite a few now but have yet to go re-dyno.
