Breathing new life into the 318 in the Scamp!
Thanks for the PM, Tim.
I think a flat tappet will be ok, too, I'm just tired of messing with it and I know that the range of power gains are nice on a roller, not to mention oil changes, timing chain lifespan/ holding advance degree and less hp/tq used to run the valvetrain.
Whatever I'm getting will end up running on the same springs you've got that are currently installed.
