The 427 is a stump pulling low RPM motor while the 396 is better for a hot rod because it has more usuable upper RPM unless you do alot to the 427. Again though, a healthy 383 built like mine is trumps both if they are stock. If you are going for all out HP, a built 427 would be the ticket, but expensive as all Big blocks are.

The guy that has this engine said he thought it had around 375-400 HP. Is he full of it?
