upgrade question.

So I have a stokish motor it rips good but looking for that scoot my ass past the grab bar stuff thinking a 4 mil crank would help. My cylinders are ported don't know by who pretty hogged out I think but clean work. Will I need a special port job for a 4 mil crank since the piston will be going up and down further? Thanks

Yup. new domes/ head and pistons if you go long rod

How much do you want to spend? It maybe hard to make those cylinders work for a 4 mil. Start with virgin cylinders or go Serval for 4 mil.
