Stroker advice

I think should start with what compromises and limits your gonna straddle yourself with 1st, like gear and stall, a lot will with 3.23/3.55 where ideal powerband is already partially chosen for you then if not flexible on cid too and build in ideal powerband, power is also been partially chosen for you too etc..

To me gears and displacement are opposite sides of the same coin, make one bigger the other got be smaller for same power/performance.
