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.





The 60403 should be good. It may be more sensitive to the fuel octane rating because it will trap more cylinder pressure. If the pressure is too high, you could install the cam a few degrees retarded (108 to 110 degree intake centerline) so the intake valve closes later.
