GT45 vs. 76mm
I'm 99% sure that the GT45 uses a 88/77 turbine wheel. It would not be bad with a 5.3 at all IMO. Should be fully lit by 3800-4200rpm with a manual boost controller. With just a waste gate spring it may take a little longer to spool.
That same cam has been low 9's and 5.80's in the 1/8th in another 5.3 with a S476 turbo. Same cam has made 800rwhp on a Dyno Dynamics dyno "easily" as the owner put it and run those times. DD dyno's are known to be heart breakers as well.

Sounds great Martin I would like to have that e.t. one day. Maybe I'll be able to find a 6.0 one day at a decent price...or I'll just leave the bottle in the car and help light the turbo or turbos.
Ive been waiting on my Milodon ChevyII oil pan for 2 months now, its been backordered. I may never know how this junkyard dog runs.
