Some info on Jim's 272 grind and the variations available for Gnarly's spreadsheets:
"The 272 cam has 232 @.050 on the intake and the exhaust has 220 @.050. The lift is 430 at the valve . It can be ground on a 110, 112, 114 lobe separation. Intake center line is 105. We can also flip the profile around so the exhaust has the 232."
I just asked him to make me whatever variation would be best for a carbed truck with smaller tires and good gearing that I want to wind out a bit 
, idle quality and bottom end negligible. Plan to use it in an engine I will make for my stock-ish 1980 pickup.
Another cam with more intake than exhaust duration.... Interesting. That's usually done when the exhaust ports flow more than 80% of the intake port flow and there are headers and a free flowing exhaust involved.
