Its been a little while.......

can you have him measure the compression height of a piston?
low compression stock replacement pistons will die with a 268 comp cam
I'd like to see a true 10:1
what say ye AJ?
do you require an off the shelf cam?
is idle and vacuum important
what gas?
around town or mostly highway?
It's real easy to overcam a 360 which makes them no fun unless you are hotrodding
you want the most duration @200 you can get and the most lift where and past where the piston is moving fastest - 70 degrees to 90 degrees ATDC.
Chevy grinds have to open the intake early to get it up that far at the correct point, so they have more duration than is necessary which comes back around at the intake close point- although not optimum you can sorta get away with this with a high compression motor with gears and converter
