The 500 HP I used in the calculation was flywheel, 450 at the wheels would get you the same results. If the numbers that Dave got on his 340 build were not on a happy Dyno I think it's a possible goal. Easy, not saying that. Weight distribution and transfer will be key. What kind of 60's has Joel run in his Hemi car with a stick and at least 700 more lbs to launch on the same tire an A body will be on? I think I will call mine David.
