That cam was fixen to bit the bullit.

if it was my cam i would see no problem running it again. was the lifter to match that lobe all right?

Lifter looked the same as all the rest. Showed picture to the guy that built my motor and he said he sees it all the time. "The area will acually hold a little oil and be no problem." he said.

Is the one in the picture the newer cam , or the one you replaced? Is it the 240 or the 250? I think I have those numbers right. I really like your 250 better anyway. If it were me, and that is the 240, I would put the 250 back in, and do what you need to to get 10:1 compression.
Great photography, and you are one busy little bee!

Whats your reasoning behind keeping the 250 (new) cam?

You will still have a high compression engine on your hands, even when you increase the combustion chamber size, and my experience with all older combustion chamber designs is that the bigger cam works better with that high compression ratio.

Plus, Lou's slant, which is high compression, runs like a scalded bear with a cam that is more like your bigger one. I'm telling you man, if you could drive his car, you would feel more comfortable with this formula, and you would never long for a V-8 again. While we did not actually go out and race heads up, Lou was convinced he had a good shot at beating my 300HP 350 Corvette. He and I drove them both, and I have to admit, he had a point. I would not have bet pinks with him. You should send him a PM, and ask every detail about his cam, and it's timing. His screen name is Dart270. His entire combo, which includes tranny gear ratios, and rear end ratio just works. Lou's Dart has the same kind of power build, and pull through the RPM's that my buddies old '67 327 powered Corvette had. Sorry about the comparison with the SBC buddy, but that was one sweet car.

That cam lobe should be just fine. I wouldn't hesitate to run it.

That said, I would run the bigger cam and spring for a high stall (3000 minimum) converter from Midwest ($400). You will be shocked and excited about the results.

I agree, its a casting goober that was there in the cam blank before the lobe was ground and surface-hardened, so its probably fine. How does the lifter that ran on that lobe look? If it is smooth and clean, don't worry. If it looks rough too, then the cam is toast.

You do know not to swap lifters around once they've "matched" themselves to the cam, right? I always use egg cartons to hold lifters when I pull them out of an engine so I can keep them in order and put them back in the same holes they came out of.

FWIW- in my experience (limited, thankfully) when cams go, they go FAST- as in "gone in another 10 minutes of running the engine." The odds against you catching one just at the moment its starting to fail are staggeringly small.
