Got my belt slip issues resolved and took it back to the dyno last night
408 10.2:1
E85
Frankenstein LS3 heads
D1SC 3.55 pulley
Aster bracket
RPM belt
Modified truck hat and Filter installed
13psi
new 897/905 @5950
old 759/704

a/f is off I had a wideband in the car and it stayed solid at 11:8:1 exactly like it has in the past. Plugs looked like I could maybe go a bit cooler, but they looked good too.
I changed the Hat and went with a shorter RPM belt. I picket up over 2lbs before when I removed the hat, but I didn't even attempt due to my ID 1000 injectors seeing 137% duty cycle.....

 

That thing is a torque monster. Stellar numbers , its an efficient setup for sure

 

That's definitely an impressive torque monster.

What sort of cam did you go with?

 

Great results! Any videos? How's the driveability?
