Tune up...What a difference!!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Finally got around to doing a tune-up on the gmc and the 72 that I got a few months back from fishead and WOW! I could hardly get the dang thing to move before. Thought it had dropped a valve or something major. Changed the plugs, wires, rotor, cap, pcv valve, and a new fuel filter and turned the key, started up first lick. Now after a few clouds of black smoke after throttle stabs, got a little tire noise. Purring like a couple of kittens.

Now for the oil, trans and diffs and they are ready for the road.
