I just got a 1997 GTP with a few mods on it........seems to be in line with the recommended stuff
Headers, Exhaust and high-flow cats
port and polished heads
comp cam with roller rockers
Msd ignition and wires
Electric water pump
Intake kit
Stock SC so far.....next mod once rattle is fixed
Retuned by local dyno shop
Problem is is has a rattle at idle, I replaced SC coupler and its still there........I undid both belts its still there, so I'm guessing that its the harmonic balancer thats gone bad, can someone help confirm this for me? thx
