I'd go the 174/250 route. You'll be right at 500hp with that change.

Ok, so what about carbs and intakes?

I'd opt for the dual plane (airgap) intake and 800cfm holley. Your mag is a great base to start from and what these guys are saying is tried and true.

BT :cool:

Thanks for the replies, I'll have to do some homework to find a source(s) for these parts, as well as someone to do the install that knows what they are doing. My first upgrade will be the prop.

I can see where this could turn into an expensive hobby :)
