500 hp from a 455 cubic inch motor is almost STOCK...

My 427 small block chevy makes 489 foot pounds of torque as measured at the REAR WHEELS...it idles @ 900 rpms - runs A/C... etc.

Taking off in first gear with 455 cubic inches "or more" is NOT going to be an issue. If you were running 800 hp from a N/A small block... that might be an issue...

This is why I like the opinions and advice from others. The overall plan for the car and engine is not set in stone. I have thrown out to my builder that I want a high torque 550+ hp with Butler Performance building the engine. Butler has a 474 to a 501ci that looks temping.
