A little off the subject, but how about both power adders? the big dogs around here are running an s-trim, with a 50 shot n20, a saleen 347, that bent some valves before he got it tuned, but it was going 137-140mph traps, before it broke, street driven with a/c and powersteering, and a couple ls1's running low 10's around 135 mph, most automatics, and blowing out rearends....doht!
its a blast watching these guys go at it though
