I think big bore is something like 6.2??? But it's mega money. Head haskets need to be custom made, your looking at $800 for them alone
By the way.. You do realize this is a 4.6 section right????

mod max used to make a stroker kit, believe it was a 4.5" stroke, combined with a dry/wet sleeve kit (max out at 3.7") it becomes like a 385 or something huge...but like said above, its fairly expensive

this is all i can find right now...

http://www.modmaxracing.com/stroker.htm


the site is www.modmaxracing.com


it says it can be stroked to a 350 which is the 5.7 but im not sure if you can get more.. thats still a decent size motor.. im sure with some boring you may get a 5.8-6.0 out of it.

Yeah I was thinkin more like 5.9L, but wasn't sure if it was slightly under 6 or slightly over. Either way it's a huge bore and will cost you a bundle but will be a bad set-up! I bet you could get 425rwhp out ofit N/A

No problem at all, the '00 Cobra R was making an underrated 385hp with 330 cubic inches. Cubes like that in one of Ford's OHC mod motors would destroy. Then imagine forced induction. Something along those lines would be almost untamable by modern rubber lol

Yeah the motor in my dad's Shelby Cobra is a 351W bored out to 392cid. He's making at least 420rwhp N/A. But then again, the car weighs under 2000lbs and the driveshaft is only 1.5 ft long!

I'm not sure what the liters are on a 392cid? Anybody know? I know the 351w is a 5.8L.
