autocomman,
in reality, with out changing the trans & rear gears,it will just be a dog normally aspirated,,your only hope to pull that bad of gearing would be to install a 292 even then, I think you will not be happy with the end result.
I understand about being on a budget,but your gear set-up needs to change.
Adding a turbo will work great with those gears because of all the added torque it will provide.
Also,w/a turbo & your gearing it will really put a load on the motor & you will be hard pressed not to go into boost w/just a bit of throttle.
I cannot think of a combo that you will be happy with that gearing for a DD on a normally aspirated 250 engine.
Maybe it's just me,but you might be OK with the very slow take-off & the 2nd gear shift @ 80+ MPH.
My moms 73 4 dr Nova had a PG & 3.08 gears & ran 20-22 sec in the 1/4,it was stock. 3000+ altitude track
If you had an early lightweight Nova, that would help,but a 69 Nova is no featherweight.This cam will work.
