The bottle neck in the Bullitt engine now lies with the cylinder heads,that's why the intake doesn't show that much gain,unless a blower is added. With the small bore,only so much valve size will fit in the 2 valve layout. Much larger and you get a shrouding problem with the side of the cylinder bore. They should have designed it with the bore and stroke of the 302......4 inch bore,3 inch stroke! The 4.6 has a bit more stroke than my 351W!!!I believe this was done more for emissions.

Also what gets me is the kind of power the Europeans are getting with smaller size engines and no blowers. They are using the 4 valve layout with variable cam timing and variable intake runner length.....that's where Ford needs to go for big power with small cubes!

I was talking about the small size V8s of 4 to 5 Liters. I agree with you on going with a medium size,300-350 inch engine for torque. No matter the size it is all about airflow thru the heads!
