What did you do with your GMT400 today...or yesterday....

Balanced injectors vs unbalanced are a far bigger impact to power than 6.2 vs 6.5.

I wished when GEP started casting they went back to the 6.2.

Bring some old oil incase he doesn’t have enough in there and a compression tester.
 
My engine is a 6.2 N/A 599 block bored 30 over. 6.5 heads. Mine didn’t have ports for either the OPS in the valley or front of the block for turbo oil feed. If the one you’re looking at is the same, you’ll need to make a T-Block fitting for the OPS and Turbo Oil Feed line using the oil port at the back of the block. I used brass to ensure proper ground for the OPS.

Yeah, that is the same as the cracked 6.2 that i picked up a couple year ago. there is some sort of restrictor fitting in the block there that's tee'd off to the turbo on it. did you need a restrictor on there not to get full flow or pressure to the turbo?
