I ain't sure how much clearance I had but it was too much & it made the oil psi drop dangerously low after a bit of running. I'm gonna tube that block/go with solids.
Hopefully it works out for you but I think the added clearance will mess with lifter rotation. We put a used 610 lift roller in my sons 360 and it runs like a beast going 6.54@3200 pounds.
