Help w/ oil pump drive?

[Will L.]

I tried to find ACL per Ferminators recommendation but none in stock anywhere. I used clevites but I had to go to 4 different stores in Vegas to get all the rod bearings. Finally have truck moving down the road and am trying to figure out this homemade TM the po of the van made. I hope to dial in boost on it tonight.

I still can't believe that after all the problems known to this engine that the cam bearing was the GM stamp and roll bearing in the new and improved engine. I wonder what bearings come in the p400.

Years ago I had a 454 drag motor and the cam bearing holes were a little on the big side . The builder knurled the back of one bearing and installed it . Never had any problems .

@NVW sorry, I never saw your question- block was undamaged, new cam bearings in, and problem solved. One thing I did was open the oil supply and return holes large in the block when I drilled them for lots-o-flow.
The bench test & road test oil pressure was back to normal specs when it went together.

I keep this next to my seat all the time:


The optimizer engine uses the crappy GM split bearing design. Im not sure if anyone makes a true 1 piece anymore. Luckily it grabbed my cam instead of the block. Yes that really is an ammo box I am using to house my tcm, vssb, and as a glove box with 4" diameter drink holders on top. Im an idiot.
