I have my 460 rated at 485 hp with the previous SCJ heads for two years. The 460 has plenty of low end torque and pulls right up to 5500 where I believe power is on decline for the factory camshaft. It's excellent in traffic where leaving the trans in the upper gears and still able to smoothly accelerate.
I know the other 460 crates with more HP have hood clearance problems due to manifold height, so fitting the correct air filter might be an issue. With the Performer RPM in a SPF there is no clereance issue. I swapped the Performer RPM for a Blue Thunder Dual Quad and gained another 3/4 inch of hood clearence with the dual chrome air cleaners.
With all the aluminum bolt-on's ( heads, water pump, intake ) the weight come's down quite a bit, but it sure fills up the engine compartment when the hood's up.
