I have done some research on parts for the descriebed rebuild.
The bore will be 0,020. Speed pro H116CP pistons is not possible to get in this size as a set. Bought each they get too expensive. also not possible to get any piston weight data.
So I will go for KB107

Regarding Cam the choice is Lunati. But I am in doubt if it shall be 60403 or 60404
Will the HP / TQ data kindly given by 451Mopar alter much if 60403 was choosen?
I want HP and TQ but is little sensitive about how the idle will be. Seeking the best compromise.
Any driven experience with these cams welcome.
