I think the idea that the cranks are causing oiling issues is mostly BS.

Stanton Racing (drag pak builder) told me the drag pak cars need 11.5 quarts between the pan and accusump. And there are at least a half dozen guys running stock 6.1 cranks shifting at 8200-8600 rpm and all have been fine for 2+ years.


Also- for those planning builds- the VVT motor cranks require machining if you want to run them in a non-VVT motor.
