Hi everyone, I'm new here. Just bought a 69 Super Bee with a 383. I was told it has a mild cam, stock cast iron 906 heads. When I bought it, it ran ok but I didn't really get on it. It idled ok. It has a brand new fuel tank with a new 3/8 fuel sending unit, but had the old smaller stock steel fuel line. I did a compression test and the numbers were not too bad but not too good. Engine definetely has miles on. compression was 125 to 130 psi on all cylinders. It came with a edelbrock rvs2 650 with an old torqer 383 single plane manifold that had heli coils for the carb studs and it wasnt straight. Couldnt get it run right WOT from stop and I wanted a 750 and wanted to change to a dual plane manifold so I put a performer rpm manifold with edelbrock vrs 750 double pumper. NO more bog, but it still lacked power. I put a fuel gauge on it and found pressure would start up at 3-4psi and then slowly drop. I put a fuel pressure regulator on and tried to adjust pressure with no luck same thing. Also tried a different fuel pressue gauge. Fuel pump looked new but looked like a china unit, so I bought a brand new Edelbrock fuel pump. Same thing, fuel pressure way too low and would go down to 1 psi. Now I'm thinking the stock steel fuel line is rusty inside so I bought a brand new stainless 3/8 line from front to back and installed it. While I was replacing new hoses I blew through the sending unit feed line and it was not plugged so now I have brand new tank, brand new steel line, and brand new rubber hoses and brand new fuel pump. Same ****!!! Now I'm really scratching my head. Now I thought maybe the clown who installed the fuel tank did something wrong so i dropped the fricken tank and found everything looked good except it didn't have a sock on end. One more test I did was take a hose from the inlet for the fuel pump and put it directly in a fuel jug and still same thing, low fuel pressue. Now the only thing I can think of is either I have two faulty new fuel pumps or maybe the lobe on camshaft is wiped out. When I installed the new edelbrock fuel pump I did measure and inspect the fuel pump rod and it was 3.21". I did notice when I put some grease on the pump rod and slide it up into place it went pretty far up so I thought I just go lucky and had it on the low spot of the cam. When I bolted the fuel pump up there was very little pressure on the fuel pump rod. So I think this guy that sold me the car took me to the cleaners. Am I missing something and is there a way to know for sure if the cam lobe is bad without taking the engine apart?
