Carb is gonna be small for a 482, so yes, you will have to work on it a bit.

Will I need to just upsize the jets or more than that? It's currently at primary jets - 73, secondary jets - 85. The 3255 is rated at 780 cfm and has vacuum secondaries.
Thoughts on where to start?

If you use the ol' 3456 rule, you're going to need to move up to a 850 to 1000 CFM. |

You're still running a 750.

Yeah, that would put me at around 900 CFM. Hmmm. Sort of hate to get rid of the 3255, but selling it would easily buy a new carb and probably go a good way toward paying the extra for that forged crank that Brent is laughing at me for.
