the shorter serpentine belt was needed after i removed the smog pump and not shown is the dart iron eagle heads i got on craigslist for a good deal, not everything in the build is there and some links might be bad though

as far as HP/Torque its in the 270-330HP range judging from racing against other cars in that power range
