should I make my 400 a 440?
I just recently built a 416EX, 11:1 piston, Stage One Hot Cams, I polished and Ported the Head and it ran the 1/8th ET @ 68 mph. He was beating Piped and Jetted Raptors and some Banshees.
Now this is with the stock head pipe with a aftermarket slip on only, stock carb, 48 pilot, 165 main. There is still a lot to gain with other tuning methods.
If I were you just go with the 416 set up.
