Nice! He sounds like a great guy and what a beautiful Duster. Good to see a stick car.

I know guys are doing that but I don’t get it.

At WOT there isn’t any (or very little) manifold vacuum to reduce crankcase pressure.

Edit: I don’t have time to watch it all today but did the interviewer ask him about the headers??

I dont get it either. But I tried a sealed crankcase with an internal fixed orifice pcv once and it stripped the oil out of the rod bearings and my oil pressure went to zero. Routed it back to the throttle body (atmospheric) and oil pressure came right back. It was weird.

Nope

Nope

I think the headers were made by Stahl #303 for Mopar 340/360. Look very similar.
