27 speed?
 
picked up a 1999 27 a few months ago with a 600 hp 502 and 2 inch shorty imco drive. I know there are a ton of variables, but why should I be looking at speed wise?

Veryhigh 70's, maybe 80-81?

With a true 600hp it better run much better than 80 imo.

I would think a little more as well, a stock 502 and normal drive will bump 70. Either way will be something fun to play with.

Not sure on the true numbers, Dyno sheet is in the boat along with build and everything else, and I haven’t even been in the boat yet. All I know is it is a 502 with afr heads, cmi headers and Holley EFI. Someone dropped some money into it and lost their ass at some point.
