The 350 LT1 in the 1993-97 Z28s are considered by some as a "detuned" Corvette engine, but they never matched the Corvette in actual horsepower ratings (not officially, anyway)
The Factory5.7(350) V8 Vortec was rated at 255 net hp @4600rpm and 330 net torque @2800rpm
It depends 9on what motor you put in it
A stock 350 CID Chevy will put out anywhere from 150 hp to about 300 hp, depending on when it was made. Or if it is fuel injected the power ratings may be higher.
The H22A has around 180-185 horsepower but not to the wheels it will put down about 170 to the wheels stock
When they made Eleanor for the movie Gone In 60 Seconds they put 750 horsepower in it.
