Dyno proven 450-475 HP. ET Guesses???

[90dpscoupe]

1bad89, i wouldnt say "nowhere near" cuz a balanced and blueprinted 306 similar to d.s.s could be near 400 at the wheels, the bottom end would have to be strengthend with main support, but his custom cam would have to be one awesome cam, i still agree you need more compression for those numbers.

My combo would be: 331, custom grind cam, fully ported afr 185's, matched to a victor efi intk, forged internals, longtubes, all balanced and bluprinted of course, and still would be hard to get 475 outta that combo, but it's not impossible.
