does ayone know how much horsepower came on the stock 1991 z28 with the 305 manual??????? i read like 240-245 but ive also heard only like 205??? which one is right?

In that year, a 305 TPI 5spd makes 230 hp and 300 lbs of torque. The automatic makes 205 hp and 295 lbs of torque. The 350 TPI automatic makes 245 hp and 345 lbs of torque.

There is a great tech data section on this sites homepage with all that info.
