4.2 liter

RE: 4.2 liter
Ah, okay. So if I got an even bigger crankshaft would I be able to further increase displacement without enlarging the cylinders? I plan on rebuilding an F150 engine (so my 3.8 can stay in my car and get me back and forth to work and serve as a backup engine when I blow this one or possibly get sold *shrug*) with whatever works out best. I don't know what is best now so I won't even plan, but from what I'm gathering forged internals is a good deal stronger and will help me reach a higher horsepower than stock, so that may be a good start. I'll also probably go with some of the same parts that I saw in that stroker kit, I think I remember seeing some polished stuff that was touted to improve performance. Iono, I'll figure it out as I go, but for now, it's rebuild the assend of my car first, cut the exhaust off after the cats (and weld the some downpointing tips on) and possibly get a tuner... and then done look for the donor engine.

So the cylinders need no machining whatsoever?
