Less than 250 and it is DONE at 5000 RPM.
Other than .040 over pistons, is the rest of the motor bone stock?
The TPI 350 used in the 89 IROC was rated at 240 HP at the crank. Probably around 150 - 190 at the rear wheels. Emissions restrictions choked those cars to death.
240 HP at the crank.
If the heads were ported and polished you probably gained 20 hp over stock. You probably have somewhere around 190 rear wheel horsepower.
it has the 350 tpi small block bored 40 over. Also how many of these were made? i was told only hundreds were made with corvette engine. Its an 89 Iroc z with the 350 tpi and t-tops.
