Well Today I decided to take my cam out, Comp Cams HE 268, The story is this: Last year I did a rebuild, reused everything, but used a different block, new rings, everything else the same, except the cam, I bought the comp cams out of reputation. after the rebuild, I fired it up, I broke it in, all ok, then I returned the car to idle, fuel started pouring out of the boosters in the carb, it flooded and coughed then died. so I adjusted the float, no avail, got a fuel pressure gauge, checked pressure, 14 PSI at idle, way to much, so I got a new fuel pump, same thing, 14 PSI, tried a used pump I got from a friend, same thing, made sure the return lines were clear, checked everything. I picked up the first pump, and took a close look at it, it was cracked slightly underneth the bolt holes, I took off the pump I had just tried, it was cracked in the same place. So I knew the fuel pump lobe was bum, so I called Comp Cams, the tech I spoke to said, "yeah it`s quite possible it`s bad, send it back and we`ll check it" I put it off until today being today it finally warmed up, so I called them again today and asked for a return number, the guy asks what`s wrong with the cam and I tell him, he says "I`m afraid that`s not possible, the cam comes out of the core master with the lobe on it, so if yours is bad, they would all have to be bad and that would be 50,000 cams" then he went on about how it had to be this or that, it was NOT the cams fault, "did you check this?" I said "put it this way, I spent $400 in parts trying to find the problem, and I`m not wrong, furthermore i`m not gonna argue with you about this anymore, just give me the return number" the Jerk goes on to tell me, "ok, but after we check it and there`s nothing wrong with it, we`ll send it back to you and nothing will be solved" I told him "I don`t care, i`m not gonna run another comp cam again" so that`s that. now, I`m not saying he`s completely wrong, but i`m afraid I don`t believe everything i`m told, especially after all this, spending money and hours and hours of time trying to find the problem and it narrowed down to the lobe, I switched fuel pumps, fuel pump rods, the whole nine yards, the first pump ran fine with the first cam, but not with this one, it`s the only thing left it could be. no matter, even if they find nothing wrong with the lobe, I will not run another comp cams product.

Did you have a gasket behind the pump flange or just silicone, I've seen that cause a similar problem.

In my personal experience I have ran 3 seperate Comp Cams, 2 of them in Pontiacs and 1 of them in a SBC. I had trouble with all 3 of them. The 2 I installed in the Pontiacs went flat. The 1 I installed in the SBC broke in two places after only 2 months. Now dont get me wrong I am in no way bashing Comp Cams, But thier reputation speaks for itself.
I have ran a Lunati in my Trans Am now for a while and I couldn't be happier with it. Crower makes a good cam also, If you can afford them.
