Not sure if it matters, but it is a V8 60 cam he is asking about.

OK, missed that, Need better magnifier. or bigger type.

I found my 3 lobe clay Smith 272-?? I measured the lift at .394". Whicch gives a Gross lift of around .375. Quite a few cams have this much lift, and I'd like to compare the duration to them. Unfortunately I can't find my copy of theClay smith cams. I was a dealer, when Red Wilson was running it.

Interesting. The timing card I have from Clay Smith states .325” lift for the 272-2.

According to my notes, the 272-2 has .325 lift on the intake and .312 on the exhaust.

Ah, right. I forgot it was a dual pattern cam. I'll try to find the card tonight.

Yep, that's what the -2 denotes.

I'll measure it again tomorrow. Now this cam was made before 1958, because that's when I gave it to Roy. The part I saved is the last three lobes. Ionly measured the intake.
