305 potential
Hey engineers,
How much horsepower can I squeeze out of the 305 if I make it a 4 barrel carburetor with cam, heads, headers, intake all changed to performance parts. I wanna squeeze out around 350 hp at the rear and about 380 lbs. of torque.
I think its possible, but would i be better off spending money on a 350.
Thanks

350 RWHP out of a 305? Do you intend to drive it?
Possible, yes. Practical, no. If you want that kind of power (how'd you come up with that number?) and still drive it on the street on a regular basis, your best bet would be a 383 or 406.
Desktop Dyno has my combo at 362 flywheel HP at 6000 RPMs. To get that at the rear wheel, you're looking at over 7000 RPMs. Meaning no power below 3000 RPMs.
Money spent on cubes almost always makes more power than any other option. Except NOx, which requires a stoutly-built lower end for that kind of power, anyway.
