You got a desktop dyno projection???? I got chassis Dyno numbers at 347hp/468tq. I mean your build doesn't sound too crazy, I'd still consider that a mild build. Bore jobs don't do much for power...I mean a .060 bore job is roughly 10-12 cubes...porting and polishing might pick up another 25-30hp. Crank and cam is probably another 50hp. Dunno what balancing will do. Intake and carb...take it or leave it...I don't really consider those to be power adders....well maybe the intake, but the carb definitely isn't...and might add another 20hp tops. So you're looking at 100hp in known upgrades...and lets say the bore job and the help of balancing add another 50hp (pretty high). So you're looking at 150hp tops. Anyone know what a stock 390 put out at the rear wheels and not the flywheel. I figure it'll probably be pretty even numbers...and it's not like the tbird is a lightweight racer.
Well, I know it was rated at 340HP by Ford in 1963 with the factory tripower (3x 2bbl Carburetors), and this intake and carb setup is way better than that one. The other stuff should add alot.
