I’m embarrassed, but I love to tell on myself. There are 3 camshafts, and 2 sets of lifters for my truck, on my bench right now. Get ready, 4 sets of valve springs, 3 sets of retainers. Any guesses how many of each I can run at one time? 2 intake manifolds, 3 carburetors. Now Im going to probably order an Edelbrock RPM, and a different carburetor all together. Typing this is actually making me feel silly.
