I don't have any RWHP numbers on my "427". It made 740hp at the flywheel. It goes 9.40 @ 144-145 in the quartermile in a 3300 pound camaro with 3 speed automatic. It has C5R heads with 14+ comp ratio.

There are a lot of variables.
I know there are tons of sponsors on here that can get you close to 600rwhp with a 427 solid roller.
The main difference between the 427 and the 408 (usual setups) is that the 408 is the cheaper and heavier iron block while the 427 is a resleeved aluminum or C5R block. The alum setup will usually have a 4.125 bore as opposed to 4.03 in the 408 which is an advantage for the 427 in addition to being 80-100lbs lighter.
