I have a 357 W,6.58 400M rods,331 pistons floating pins...Bearing clearance is .003 on mains and rods,milodon drag race pan/pickup....I have every intention to spin it to 7500....What oil pump would you run,based on experience?? Windage tray??  I've had good results on 302's using a standard 5.0 pump with no issues,but the windsor does have a three inch main bearing....

  I know this topic is about 3 months old but I was wondering if you got it together. I built a couple of these engines. Mine revved like a 289 on nitrous. In my experience if you're going to zing it you need a good mechanical oil pressure gauge. Keep an eye on the oil pressure. If it drops 5 psi or more & an oil change don't bring it back up you need to check the bearings. The first one I built did that & I kept on driving & racing it. Well, it blew up @ about 7,200 rpm going through the traps at the end of the quarter mile. The cause was a burnt rod bearing. The second one I built lost 5 psi so I pulled it. It had a rod bearing going bad but at least it didn't blow up. I abused both engines severely. They saw 7,000+ rpm almost every time I drove it. I hope you enjoy yours as much as I did mine.  Oh, the oil pump I used was a melling M83HV.  Have fun!
