Since you guys have given me some good advice for my LT1 turbo project, I figured you may be interested in the results.
Here are some pics-
Basics of the buildup are 357ci, AFR heads, 214/222 hyd roller, 9.2-1 compression, FAST bank to bank with WB o2, dual intank walbro 255's and 83lb injectors, Innovative GT80BB 1.32 A/R, Innovative indy gate, 6-speed, 3.42 gears.
Allthough I havn't got the boost controller installed yet, I strapped the car down on the dyno and was just using vacuum t's in the wastegate line to vary boost.
With 100 octane, it surged to 20 psi at 4,600, and then dropped off to around 16.
It made 645rwhp at 5,070 and 700rwtq at 4,650. Both HP and torque lines were on a steep incline until boost dropped.
Hopefully when I get the boost controller installed and see some steady boost it will lay down some REAL hp
