Works great on my Auto.
Replaces main crankshaft Harmonic balancer pulley and drive belt. Prob 20 hp. SC spins up quicker, couple more lbs at max too.
Plus on pre 2000 needs uprated fuel reg and colder plugs plus MAF relocation kit (moves it to same place as post 2000.
All supplied if you give correct onfo.
