Sneaking in without a roll cage

It'll blow the street tires off.

That's possible, tho he has E.T. streets, hardly "street" tires.
I would sure try to get some 275s under it, the typical "small tire" 10.5 style drag radial.
And imo, et streets kinda kill the sleeper vibe.

My gts has 235-60-14 DOT bias plys on it in the pics I posted. Hooking an automatic at that power/weight will take some good shocks/suspension tuning but it should not be a major hurdle. If I can hook at no prep with a 4 speed on nitrous the OP should be able to make it happen on a prepped surface.
