Okay, let me go over what it is, and what i've done to it. It was a two barrel
(Rochestor Dual Jet) carb 267 V-8 originally. I replaced some leaking gaskets (Oil pan/timing cover and valve cover gaskets) and while I had the pan and cover off I went ahead and put in a small cam from Summit. I also bought a quadrajet from Summit and put it on a factory cast iron intake. It has the HEI distributer that it came with when I bought the Camino.
I have checked to make sure that the throttle opens all the way, the blades do when I manually move the linkage. But not when I give it full throttle with it running, as it isn't making enough vacuum to open the bores up.....it's only a 267 after all. lol
I've tried this driving and with me under the hood in the driveway, and it still does the same sputter/choke out around 2500RPM. With me working the throttle at the carb, or at the pedal.
I can't check the timing at idle since it's not really idling, but it was at roughly 25 degrees on the timing marks yesterday, with the advance capped off. I put a vacuum gauge on it, and it was pulling a steady 18 pounds at the fast "idle" that is has right now. Drops down to zero when you open up the throttle.
I didn't think that the open gasket would make a big diffence, but thought i should mention it. I don't like, or use the paper gaskets either. I like the thick ones, so the 4 hole one is the same thickness as the others.
I'm starting to get frustrated with this vehicle, and have thought a couple times about just shooting it to get it out of my misery! lol, just kidding. It is frustrating though! :dontknow:
