I have also driven some big blocks and they had nice torque on the low end, what was missing on the ones I drove was the blistering acceleration above 4500 rpm, the stroked 427's seem to explode above 4Krpms. The big blocks acceleration appears linear where the small block is exponetial.
Now go with a KC 482 with 600 plus hp I think you would have the best of both worlds if you did not kill yourself.
Might want to call Eric at Performance Engineering also, he builds some nice motors at competive prices.
I have learned at times when dealing with corporations the guy / gal on the other end does not have the same equity into the deal as the business owners themselves. I am led to beleive if you call with a problem you are not going to be talking to Henry Ford or Jack Roush, maybe, but I doubt it. You call KC or Eric at performance engineering you will be talking to them, the guys that can make a decision in an instant. No other approval required. Look what vendors post and supports on this forumn.
