Just bought -74 Camaro with following specs on the motor:

-454 LS5 from year -71
- Mildly ported/polished heads with stock size valves
- Efelbrock aluminium intake
- There is some kind of "torque" cam inside with ~0.500 lift but I do not know about duration
- Holley 750 db
- Hooker headers
- 9,5 CR new pistons

So does anyone have a idea on how much RWHP there would be in the motor like this?

Car has 3.73 diff, Auburn lock, TH400 with shift kit and Mickey Thompson 26x10.5x15 street slicks.

Any idea on what it would do 1/4 mile?

Thanks,

Mike

somwhere between 390 and 450 Hp, depending on cam quartermile time should be in the low 13 to high 12 range, but could be lower depending on converter, tires, weight and driver...

my guess is 12.9
