Any LowBuck but STRONG overdrive option?

i'm with AJ...904 with low first and second gear.With that hp in an A body you should be able to run
a 3.23 rear gear which will be the same as 3.6:1 in first but final drive is 3.23.
The fly in the ointment would be if you had a long duration cam which would kill lo rpm torque.
What cam are you running?
