what des it take to stroke a 360 to 408?

The size of the engine isn't holding you back. The execution of the build is.

Boy! Talk about the quote of the DAY! You couldda actually said this same thing to Chrysler regarding the 400 engine. LMAO. I mean....with a few tweaks, they will scream. I couldn't agree more. The actual difference in a drag car between an all 360 and an all out 408 I bet would be less than half a second. Course, when you're drag racin, that's like ten years. LOL
