Lots of variables here.
Pump?
Cooler?
Rpm?
How much work has been done to engine?
Weight?
Water injection?
To name a few

If running a ford you probably want to call Forrester’s in chambersburg pa

I agree with contacting Forrester’s.

Imo you’ll need a better pump, A or preferably P if rules allow.

Make sure when you call you have all the rules for your class so the builder you speak with has an idea of what is possible and needs to be done

3x3 is good with its numbers and a 3x4 has its numbers. What are you trying to accomplish is the question. Championship or fun. If you are asking then its not a championship. Stick to the 3x3 and do all your experiments there at phase 1. Like HELP said to many variables and that's a few out of a hundred things. Good advise listen and only change 1 to 2 things at a time. This will help you find your way on what works and Doesn't and of Coarse who knows and who doesn't.
