BB Mopar Oil Drainback Modifications???

Sounds like to much oil pressure, put in a softer spring in the pump.

I have run the Indy heads on 1/2 Stroker 440 with just a Milodon pan and pump
with only eight quarts. I run Mobil on 10-30 synthetic with Zero problems.

I had issues with Oil foaming and nearly emptying the pan only when I ran a 15 - 50 Conventional Non syn. oil early on with the engine. I do not know if it was
the higher oil pressure or the foaming slowing the return or possibly
both working together that was the problem.

I since have broken the engine in and change oils before making a hard pass
on the bracket cars.

Hope this Helps!

I started to think about when did i start having this problem. I think it is from the Main stud girdle that i put on it. not enough room for the oil to drain back at a fast enough rate. it was probably acting like a second windage tray. now i purchased an aftermarket mega block. so bye, bye stud girdle. What oil pressure would you recommend? i have an adjustable milidon spring set up in the pump. i usually try to limit to 80psi going down the track.

Milodon system run on Steins cars back in the day, never went over 60 # or it would empty the pan.
