Greg thanks .. What would your numbers be for a 650 to a 670 lift .
I have learned that if you max flow at .650 lift that
you would like about .750 lift on the cam(at the valve)
because your at the .650 lift a much longer time
(you pass the .650 lift point 2 times and all the time
between) for better filling specially at RPM when you
have a shorter time period to fill... also the .750
would be a decent starting point or higher

The problem with those shelf cams is if you want the
lift the duration goes up with it... if you knew
the head flow and what rpm you wanted to turn would help

I don't think you need to go more than a R-282-286 on the duration. Lift will be determined by what the heads flow and at what lift. Some engines like less lift and will actually run better with a shorter cam because of how the heads flow. What overlap or lobe separation have you decided to go with? What is the compression of the pistons you ordered.

the air flow I have to guess now ,, but from what I have read it possible will be around 320ish

I used a Comp Cams custom grind solid roller cam in my old pump gas Duster motor, it was 260@.050 intake with .420 lobe lift, 266 @ .050 on the exhaust lobes with .409 lobe lift. 108 LSA in at 106 to 107 on the intake side  I used a set of Harland Sharp 1.60 ratio(actually checked to be 1.65 ratio at the retainers  ) rockers, that combination flat rocked . My message is sometimes more duration is not the answer, more lift on BB Mopar heads does help fill the cylinders well   Camshaft picking is a art, just like converters can be  On your deal I would look at a cam with 268 to 274 @ .050 on the intake side and 274 to 278 @ .050 on the exhaust side with as much lobe lift I could get on both lobes, ground on a 108 or 110 LSA and install it to start with from 104 to 106 on the intake side :twocents :Make sure and get the best valve springs and pushrods out there

At what lift... that'll say how much lift you need
if you want to go all out

I think they are way to big for your combo.
