I REALLY miss the power of my 11-sec T-Type so was thinking LS turbo, but don't want to drive around a gutless turn when off boost.
the 5.3 with just a cam and springs change was running 8.20's at the 1/8, 3.55 gears, 1.90 60' time with nittos, little motor was pretty stout and move quick, when I installed the ebay gt45 turbo it was defenetely a beast, But I am not a tunner so I over boosted the little motor doing a burnout, showing off to my coworker and damaged the P. rings, car drove fine, no over heating.
I am sure it would have run low 11's maybe 10's, the 6.0 I didn't really have a chance to drive it, my buddy came over and convinced me to sell him the motor for his rs camaro, tell you true I wasn't happy with the ls in my car, now I am it's gonna have a 455, Edelbrocks, roller cam, undecided on trans th400 or 200r4.
