My truck is running fine, but my 79 Corvette, is another story. I am in the process of removing the Holley sniper system, and replacing it with a Carburetor. I am sick and tired of the issues with the Holley sniper. Working on a Corvette, even an old one, is not like working on anything else. It took me a day to pull the electric fuel pump, out of the tank, and replace it with a new sending unit, for a Regular fuel pump on the side of the engine block. Installing that, took my another day. Tomorrow I will install the new Edelbrock AVS-2 carburetor. The issues with working on a Corvette, is room. There isn't any. No way to fit a ratchet in a lot of places. The best you can do, is a regular wrench, and then you can only turn it just enough so you can get another bite, once you take the wrench off. Just 1 click at a time. But, I'm not bitching, it is, what it is. Most shops will not work on a Corvette, at all, B/C of how much time it takes to do anything on them. But, once your driving it down the road, it's all worth it. My car is very fast, and very responsive. Runs 12 second quarter mile times, and takes a corner unbelievably well.
