Any low 11’s 6 - Pack cars on here ??

For up to about 3500lb race weight, figure on making about 440-450hp, uncorrected, as the motor sits in the car on the starting line.
Cam/converter/gears....... all on the same page.

If I were building it, it would be something like a 10.5:1 stroker, RPM type heads, SFT cam, headers.
I would be targeting 475-500 STP corrected power on the dyno.

That’s based on the assumption you’re not racing at a high attitude track.
