Help Choosing a Cam/Converter- 9:1(ish) Stock Stroke 400

[JG71B]

Theoretically the KB240 pistons sit .025 in the hole. They milled a little less than that off my block to get it to zero deck. My numbers with 89cc heads and a .041 gasket are just a hair under 8.7:1. I substituted a .020 gasket and it came in just over 9:1.

Yup! But is that stock with 400 stroke or 3.75 RB stroke?
