I love everything but the grill (I say black that out as well)
Estimates now that you went with a 91mm turbo on that many cubic inches.. 8.50's@160+, I would imagine power to be in the 1,1xx on 20psi and good gas.
also.
with that big of an injector I would run E85/E100. I would have IPS Eric do a tune for it for sure, he is a wizard on them damn chevys!
