I went with their H13 pins. The wall is pretty thick. I think they set it up for the power goals I have. I just asked them for gapless rings. No idea what material they used. It's total seal racing rings. They sure weren't cheap though. LolWe’ve actually made 350 a hole with those slugs. Same design just vertical ports.
They hold up great and don’t beat the cylinders up bad. When you make real power a full round piston like those works best.
What pins did you get? We use the trend pins that are .250” wall.
Also, I hope you didn’t let them “up sell” you their “top” ring pack. We use the gas nitrided moly faced rings with a custom cylinder finish. We blow less into the can than anyone else running the power we are.
I don't think the engine uses that much oil. I looked at other racing oil pans and they had about the same size holes.Great build! That pan is nice. Might consider throwing some more/bigger holes in the top of your tray though. Want that oil to return quickly and not get caught up in the rotational assembly.
The pick-up comes with its own bracket for clearance.That’s pretty wild! What did you set the pickup clearance to bottom of pan at?
