As i reread this post it sounds to me like your oiling system may be inadequate. What ever you do, set up some form of warning system for oil pressure below 30 psi or HIGHER. With what you have discribed as an engine package, i would think you need a ten quart well baffled pan, and maybe an acusump system with another couple of quarts to stay out of trouble when braking!

I'm trying to understand why he would need all that when I've been running a basic 8 qt. Moroso pan usually with 6 qts. in it and a windage tray street driving the hell outta my car forever and zero issues past 7000 rpms..........

Ok, I got the bottom end taken apart. I am thinking that the bearings that were coated with a friction reducing powder coating made the clearances too tight. The black on the Thrust bearing is the remains of the coating. So, is the crank worth saving? Can the rods be safely ran after they got this hot? Moral of this story is don't listen to someone that is trying to sell powder coating and has no idea about engine clearance.

They only sell the coating. The engine builder is responsible for checking and setting engine clearances

Haul the whole thing down to Grays Automotive in McMinnville and let him set it up for you. Looks to me like you have some good parts but it wasn't set up properly. Now you probably need to have the crank ground and buy new bearings. Might need to hone the cylinders too. Looks like the clearances were too tight everywhere in that engine?
Have Grays assemble the engine for you and then do a dyno test before you put it back in the car. That way you'll know it is good and ready to run.

When it was going together the clearance on the bearings was in spec but on the tight side. I should have stopped and bought new bearings at that time. Digger73 (Mike)

I would be more worried about all that blue silicone! I know there is alot but that was what I was told to use to seal the block to the main griddle. There was no leak and the Oberg showed no signs of silicone so no harm there. Digger73 (Mike)

I am still sort of new to this area and had no idea what shop to trust. Do you think the rods are salvageable? They have hot spots from the bearings. Digger73 (Mike)

Load the stuff up and take it to a reputable machine shop. By the pictures, the crank doesn’t really look that bad to me. Most of the stroker cranks I’ve installed have had the bearing clearances way on the tight side. I’m betting that’s what has happened here. Heck, you might just be able to inspect the crank for cracks and excessive wear and if all checks ok, and give it a polish and install new bearings that provide proper clearance and go.

Well I know it has been a long time but I finally got my engine back together. The rods and Crank were redone by the same machinist that Andy F suggested. I have to give him two thumbs way up to him. He did a first rate job in fact maybe too good! I just got back from Woodburn. They told me not to come back until I am ready to license! The car is a 1970 Plymouth Road Runner. Please ignore the Reaction times... Thanks to all that made suggestions and gave me input. BTW this is the first time the car has ever been on the track.

Well I will be there with the car but I was told I can't run it until I am ready to license. I would love for you and Paul to stop by and take a look at my car. I will be running my daily driver a 2018 Challenger Scat Pack. My Challenger is white with blue strips. Hope to see you there.

Take some timing out of it or disconnect the secondaries. Promise you slowed it down and they should let you run.

There are many ways to slow a car down at the track, short shift it by 500 to 800 RPM, over rev it several hundred RPM above the best shift point, let off the off the throttle on the other end or on the starting line 30 to 50 ft. from the starting line. Put weight in it, put more air in the rear tires, deep stage the same every run, lots of options to slow the car down

The next option is that I am going to see if I can start my licensing tomorrow.

Thanks Cab! That is something I was sort of worried about. See you there.
