How much horsepower???
Ive been trying to figure this out
ive been trying to figure out how much horsepower my car had stock from the factory
Its a 91 z28 convertible- 5speed
now edmunds.com which is usually accurate with horsepower says its 230hp
i believe that my car also has 3.08s stock
but the charts i find everywhere online says the m5 z28's that come with 3.08s have only 205hp...
I know up to 1990 the 5 speed 305's got the better cam that gave 25 extra hp
but mines a 91 so i dunno, could edmunds be wrong...
THey didnt offer g92 packages on convertibles so it cant have 3.42's in the rear
anybody actually know?

if you are positive it doesn't have the G92 than that is what you have.
crawl under and spin the rear tires, count the drive shaft rotations just to check
