OK I know I am supose to be the expert here but I know some of you have had more experiance with this than me. This car is killing me.
I have a night mare of a car it is a 383 built for boost with D1SC at 10-12lbs. The new GM crank pulley was keyed and installed. but everytiome it gets into boost hard it spits the pulley off the car. This time breaking the bolt in the snout of the crank. The car has barly seen 100miles with boost and I have replaced the crank bolt 3 times and even drilled and tapped it bigger and replaced the hub twice. I am my wits end with this car and need a solution to keep the pulley on the car. The car will be mean if we can keep the crank pulley from moving. It stayed together long enough at 6lbs to dyno tune it and it made 600rwtq. Any help would be great.
Thanks Guys
Nate
