Solid cam damage diagnosis help

If a customer told me a cam I sold them had .007” lobe taper...... I’d have them send it to me so I could measure it myself.

Quite a few years ago I sold a solid roller to someone for a SBM.

The motor had gotten freshened up and they wanted to try something else for a cam.

The car ended up being slower.
For some reason they decided to check the lift...... and it was short.
Way too short, even considering the 59* bank angle and .750” offset int rockers(W2 heads).

They pulled the rockers off one side and checked the lift at the pushrod....... it was off by a good amount from the spec..... like .025-.030.

I had them send it to me....... because I thought that was “impossible”.
I put it in my lathe to measure the lift. It was dead on.

After a few phone calls and some more checking we determined the base circle of the new cam was a little shorter than the old cam........ and the lifter link bars were touching the top of the lifter bosses, which didn’t allow the lifters to drop all the way down on the base circle of the cam.
They didn’t want to have to grind on the block of their freshly rebuilt motor to use this cam...... so they put the old one back in.

I’d have also thought that a SFT cam with .007” taper coming from one of the well established cam grinders was also “impossible”...... so I’d have wanted to see it for myself.

Sometimes...... strange **** happens.

“Duly noted” seems a lot like “we don’t care”.
