My 422 smallblock build

And yes I’m using ARP main studs and I did not have it line bored. GASP! I can spin the crank with two fingers.


That thrust is a bit tight for me. Make sure the studs aren't forcing the cap to the front or rear and changing into the thrust reading.

I always set the thrust by leaving the number three cap loose and with a rubber mallet or a dead blow or something and a piece of wood and gently smack the crank to the rear and then back to the front and then torque the cap.

Like I said... That's on the low side for me. .004 is my minimum. You've got to get some oil in there.

Edit: 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. If you are at .0025ish you may get by with it if you are getting pressurized oil in there.
