Gearset,
Here are some computed numbers from my DeuceCoupe Gonkulator.
It matched up fairly well with Tom Lowe's recent dyno testing so here is what it computes for:
Stock 250
Torq 224 at 2300
Powr 152 at 4000 (rated 155hp)
Add Offy 4v, 390 Holley, headers
Torq 227 at 2800
Powr 173 at 4600 (gain of 21)
Add Clifford 264 cam (206-206 duration)
Torq 241 at 3400
Powr 201 at 4800 (gain of 49 total)
Or Clifford 270 cam (214-214 duration)
Torq 241 at 3500
Powr 207 at 4900 (gain of 55 total)

Then of course there's the head....
But first, what vehicle is it in, trans, gear, exhaust, usage, and weather (doesn't it get cold up there???) Big cams are liveable in the summer but a nuisance in the winter.
