I purchased a balanced 383 rotating assembly for my 95 LT1 Camaro that came with the flexplate and harmonic balancer but my crank pulley will not bolt up to it. Basically, the pulley is the same diameter as the balancer so it will not mesh flat to the bolting surface. Could someone tell me what pulley I need to make it work? Thanks

 

I just got off the phone with CNC Motorsports and they said they sent me an external balanced rotating assembly by mistake. Now we have to swap it out for an internal balanced assembly. Looks like another week of waiting.
