This motor (LS1) is good for around 345 or so crank hp... 300+ rwhp... in an otherwise stock trans am, convertible... weighing in at slightly more than the VX... mid 13's are not hard to overcome... of course, I will have to do a little more overcoming of the wind... but will have less weight to push... it should prove to be intersting. BTW AlaskaVX... have you dyno'd? Just curious what kind of turque rating you have with that 275hp... the LS1 is up around the 350lbs of torque and that is available at around 2000 rpm's... probably quite a bit more than the 3.5 with SC... but I could be wrong. I'll definitely take it to the track though. Once its running... I have to come up with money to get LS1Edit... tuning program... cost is $450 for unlimited vehicle lifetime tuning at one of our local shops... they can adjust EVERYTHING in the PCM... heck, once my gauges are working right (hopefully someday), I can have them calibrate my speedo and everything... I change tires, they can plug in and fix it! No, its not cheap, but in the long run, if I plan to keep it... its well worth it.

TTYL!
