direct replacement for any 5.0 +5.7l vortec engine no matter the model of vehicle. cap, rotor and cam sensor included.

seemed fitting as i already had wires, control box, coil and adapter harness. isn't it beautiful?

and rotor attachment screws should lightly loc-tited before cap install. factory forgot that on mine and i forgot to check. one day massive pinging and stall on the freeway when rotor lifted and contacted cap and spun the assembly right of the shaft. http://s1222.photobucket.com/user/S...Tahoe 4X4/MSD Dizzy 1?sort=3&start=all&page=1

Going to do fuel pressure test, change the plugs, and check the distributor today or tomorrow. I'll do some research on the injector balance test and how to do it.

Thanks for the answers so far

need a pressure test unit and a scanner with gm bi-directional controls to tell the pcm to fire the injector while watching the gauge. you fire it twice and record your pressure loss. re-prime pressure and then another injector and so forth.
