how fast will my truck be after the swap

[jimmy p]

Just curious...whenever I get an ls1 and drop it into my truck how fast will it be as far as top speed and 1/4 mile time. Its an 89 chevy standard cab fullsize. I have a parallel 4 link plus the batteries and fuel cell will be relocated further back behind the axle. Say I do the computer tuning with ram air and exhaust to a basically stock ls1 with an auto tranny. Any guess-timates?

gearing, traction, weather all play huge parts in that so giving an accurate guess is hard to do. i wouldnt worry about it running 15's & 16's if thats what your worried about. cars will run 13.7-14.0 range most times, add a few hundred pounds and you should be around mid 14's after aerodynamics is factored in.
