Don't waste your time with a 6 pack.

The real question is what's wrong with what you already have. I doubt I would have used a 650 just because the booster swallows bilge water but that can be addressed.
could you educate me on that?

Now whether you go with efi or a bigger carb, you combo need to be dialed in first! as has been ask do you know you initial timing, how about total timing? this would be the first you need to know. Do you have a timing light to check?

OK let me Back Up a little bit here. You have the eng in the car? if so, what is the least exciting part about driving it?
What part of driving it, do you want the motor to do better?!
answering that, will help us all, help you..............

I would like to see a stronger acceleration. It's got power as it builds rpm but the acceleration and power to get up and go at the drop of the dime almost always requires 2nd gear. Off the line I know it could do better. I'd like to chirp the tires with ease as I shift from 1st to 2nd or even be able to break traction without popping the clutch.
What does it mean, to swallow bilge water??? And what booster are you referring to? The car is down right now in body/paint restoration I can't check the timing at this time.
I found my build sheets;
I've got Pro Comp Heads Made by Speedmaster. Don't know the specs other than 2.02 intakes and 1.90 exhaust
The carb is by quick fuel techno Street performance carb
The Cam is a custom ground cam. Intake lift .525 with 279 duration exhaust lift is .530 with 287 duration. Lobe center is 109 Intake c/l is 103. On a second page it states intake gross lift at cam. 350 with duration 227 exhaust gross lift at cam is .353 with 235 duration
