Review on AcPulse Complete Ignition Distributor for Chevy GMC Vortec 1996-2002 V8 5.0L 5.7L Models - C1500 C2500 C3500 K1500 K2500 K3500 W3500 W4500 - Black Cap by Daniel Anderson

On my 99 suburb I had to dismantle the manifold several times. Camshaft and hydraulic valve lifters were recently replaced. The distributor is hard to get to, if it's off more than 1 degree the check engine light will come on and since the timing is computer controlled you can't use the light to align. This replacement is used for correct indexing. Much easier than trying to tag a standard unit and hoping you get it right. If you need to remove the distributor for any reason, it's well spent.
