Default Motor idea ...

4.030 with a 5.3 crank.

How you think that would run?

It'll be a 370cid 6.0.....the 5.3 crank is the same as a 6.0 crank

Now the 4.8 crank is another story....4.030" bore x 3.286" stroke = 333cid 8000rpm toy, Run a T-ReX or G5X4 cam and spin that puppy !!!

I'm thinking the FAST intake, a custom Crane 242/248 .610/.610 112 cam and Stage III Patriot Heads, According to Dynosim that combo will net you 546hp @ 7000rpm and 498 ft/lbs @ 5000rpms....not too bad for a 333cid motor

I dont really see it making that much power but I bet it would run damn good. Thats an absolute monster cam for a 333CI engine Thats close to what I was going to switch to in my 418

I don't know.....you spin it that high and I bet it'd make ~550hp.

I dunno that I would be able to tune that cam in for that little of a motor. The 233/239 was hard enough and still cannot get just right.

I'll have to think about this though.

That would be sick!! Youd need a pretty aggressive converter though, it would probably feel pretty lame lugging around town

Patriot heads are a no go. No way I'll run them.

I'm thinking AFR 225's.
