Hello everyone!

[Lofty]

No.. it's not 4AGE.
I found out the engine he bought is a 4AF Crate engine made in california. Basically useless for my build
But I have an idea.
I want to build the 4AC engine, he already has a ton of parts for it, like a clutch, flywheel, gasketset, new bearings (Thats what the engine needed).
So here's what I'm thinking.
I want a new carb set up, What should I go with that would bring the most HP?
Are the 4ACs cranks internally balanced? How does an underdrive pulley sound?
I am going to Port and polish the hell out of everything to maximize volumetric efficiency.
Intake and filter will be a must.
Header and exhaust will be good too I think.
Lopey-er cams and better springs help a lot I've heard.
Is the fuel/oil system good enough to handle sideways forces of drifting?
Is it okay to weld my diff?
Any other ideas that will help me stay in a reasonable budget and keep up with the 4ag guys?
Thanks a ton guys!
