Does anyone happen to know what kind of #'s a stock LT4 would do on a dyno?

 

i think the stock lt4 corvettes were listed at 330 crank hp, so maybe around 280-290 to the wheels.

something seems strange with those hp and tq #'s. They all seem too low. Like that 383 only making 363 hp. Oe this 396 with 10lbs of boost...396 stroker, ATI P1SC w/10lbs, intercooler, 58mm TB, port matched heads w/
2.02 and 1.60 valves, 42lb. injectors, MSD 6AL, Crane 222/230 cam w/ .542
and .563 lift, 9 to 1 JE/SRP pistons, Callies crank, Eagle rods, McLeod dual
disc clutch w/ aluminum flywheel, 1 3/4" long tube coated headers,
flowmaster exhaust, dyno tuning with Norris Motorsports....no way did this guy only put down 447hp.....it just don't seem right to me

 

most dyno in the 290-300 rwhp range
