sorry if this is a completely stupid question, but are those numbers on an engine dyno?? What was the lift on the cam?
reason I ask is those are pretty wicked numbers for an auto, small cam (for a 408) and 3:73s if those are whp.
did you guys do the shortblock?

Sweet power. That is well over 600 rwhp with a manual transmission.
