Another 318 set up

I think what would more suit you is 80/90's 5.0l mustang/tuned port iroc type thing, which our closest match would be 5.2l/5.9l Magnum, I had a 5.9l Jeep Grand Cherokee Limited, she pull hard in the jeep in a light little A body she would be perfect, could even do a slight cam regrind, mild porting and headers run it with OD and some gears, either with reprogram computer, or sniper or carb, call it a day.

Modern engines try to make power mainly with heads and long intake ports for low rpm torque, the cams they run are pretty small, wrong cam is more likely gonna make a combo have poor drive ability more so then just about any carb heads intake etc.. you would likely run. But doesn't mean you can't run a reasonable cam it's just better to make the majority of your power through other means. Aka top end carb intake heads headers cr etc..
