My 422 smallblock build

I forgot to mention that Ramm I think it was and maybe MoparOfficial too drill a small hole in the bearing and block where the oil feed goes up to the cam bearing to get pressurized oil to the back side of the thrust.

I’ll have to look into that mod. If you happen to find a post or thread that explains it more please post a link here.

That's going to be a whole lot of fun there, what's that going into?

This engine will initially be put in my 72 Duster with 4 speed and 3.91 rear. I have a rough 70 Swinger that my son and I hope to build into a 70’s ProStock style race car that may eventually get this engine.

Glad you are on your way and I look forward to following your progress. I’m not an expert by any means but .025 endplay would keep me awake at night.

I know .0025 is on the tight side but it is within the .002-.007” spec. I will probably fiddle with the caps a bit to see if anything changes but I was pretty careful the first time to get it right. I tightened the rear main first and worked my way forward, skipping the #3, and worked it back and forth. Then held it forward and tightened the #3 cap.
