Go to street cam from the 70s-80s.
@yellow rose , doesn't Mike Jones have a great cam for a mild 318?
@S.Rodney you might want to put his name in the search box and see what comes up here. I am sure there's info about that cam on a 318 cam thread.
Mike has some really cool lobes, especially in his inverted flank series.
I shouldn't say this because it's hard without name dropping and we all know what a SIN that is so I will do my best to keep names out of it.
MFI 377 CID SBC around 1984ish and some inverted flank lobes were on the market. It was all the rage. I did probably 4-5 hours of phone calls to make sure I wasn't stepping on my weenie with these IF lobes.
Everyone and their mother said go for it. Those lobes will pile on the power in the mid range and still pull to 7800 where it needed to be.
They were wrong. I now know why. Didn't then, but I know now. On the dyno the intial numbers were looking spanky. Except about ~ 6800 or so. Then the engine would change tone, and was getting pissed off.
A quick check of the valve springs and they were toast. Get new springs and they don't do much better.
So we crap canned the IF lobe and went with a Crower lobe IIRC and the engine came to life.
The issue with the IF lobes back then was there was essentially one originator of that kind of lobe, and that was Jones. IIRC it was his father that developed it, but I could be wrong on that. It may have been Mike himself who came up with the idea, but I think it was his dad.
At any rate, the lobes we were using were a copy of what the Jones lobes were. It's very difficult to copy a lobe, and the IF lobe is near impossible to copy.
When Jones developed the lobe (there goes that name dropping) they had a completely different way to grind those lobes. It was expensive and time consuming.
The other cam grinders just tried to copy those lobes with what they had. And it sucked and gave the IF lobes a bad name.
I have no doubt that a Mike Jones Inverted Flank roller lobe would be a damn good lobe. Maybe some day I'll try one.
