318 stroker
Pro's and Con's huh? Whew! Alot can be writin on that topic and strokers. People will scream "Rod ratio" and thrust surface wear. But I really don't think your into the sci. of it are you?
My biggest con on strokers is price.
My biggest pro to strokers is bigger the better, more the merrier.
Con on the build is the Edel. heads are just about enuff to feed a 360 nicely. The 390 with the smallish cam could probably do well with some prep work on the heads and possible bowl porting if the wallet has it.
I think this combo is super streetable with tons of torque. Though you'll make peak power before 6000 for sure.
