426 stroker kit

I think the 4.125 is used for the 440, but I could be wrong. I'll have to re-fresh my mind on some of this, but it doesn't make a difference for me as to what will work with an iron Gen3 vs. what will work for a long time in an iron Gen3.

It all gets down to what engineering knowledge you may have or who you want to believe out there. When I told my first engine builder my goals for my Cuda (plenty of racing with a manual trans and slicks) and couldn't decide between 392 and 426, he said definitely go 392.

I plan to bring my old engine building skills back into use on this 426 for my Challenger and decided on the 426 because I won't be beating on it as bad and there's already plenty of 392 SRT Challengers out there.
