Sounds like normal start up pressure and warm pressure to me. Starter has zero affect on oil pressure. Now if it dropped to single digits after warming up, you've got a problem. So drive your Challenger and enjoy!
Not to still your thread. And thank you for your service:
I'm working on 300,000 on my 70 Challenger! I've got less than 50,000 to go! 😀
She smokes a little at start up, she's got a few squeaks and rattles, but she still barks the tires between 1st and 2nd gear. Transmission was rebuilt about...
@Challenger RTA, I agree. Any vehicle that is a true daily driver is going to run decently enough to pass smog. It's just another tax on we the people! I won't even go down the "emission devices" road as once they started putting smog pumps on the cars, I knew it was a scam!
Mom had a 75...
Bill, keep us updated please! I think if you can keep them reasonably priced like you estimated, they should sale well. They will work great on all small blocks including the magnum engines!
I use this $20 extension. I even drilled an extra hole in one to use in my 64 Imperial with the rear pump. Maybe it's just because I live in the heat and I'm always wanting to keep things as cool as possible! 😀

If a bare block is std bore, .020" or .030" oversized, it's probably worth $2-3k. More (double) if it's somebody's matching engine like 72 AAR Cuda mentioned. If it's .060" over and needing to be bored, it's a boat anchor. Even .040" and needing to go to .060", a wise man would have is sonic...
I run the deep pans from RockAuto built by Dorman for the 96+ 46re transmission. That pan has small 1/8" ribs built into the bottom and a drain plug of course.
Type F, Dex/merc, ATF +4, Dexron 3, etc. Chryslers three speed automatics are the toughest ever made and will run on just about any automatic transmission fluid!
If you don't mind spending a little extra money, I highly recommend getting a deeper pan from a 90's A500/42rh (if 904) or A518/46rh...
When you replace the tail shaft housing, you'll have to remove the two Phillips head screws (just above the red circle in Vannth's photo) to access the big c-clip ring that holds onto the output shaft bearing. It can be spread about with needle nose pliers or a pair of large snap ring pliers...
Don, I sure hope you're running aluminum cylinder heads with that 11:1 compression! Either that or race fuel!
Make sure once you get the short block built, you use model clay and check the valve clearance! .600" lift is quite a bit! I usually do this without the head gasket and the head bolts...
It wouldn't be horrible if he bought it! And us "old timers" can help a lot! I have some Challenger interior parts that are well used that I could supply for shipping costs @deathproofdodge ! 🙂
