When gas got spendy in the 80's, I rebuilt my 440-6 engine to pretty much stock except with a set of low compression pistons. I measured it up & it was in the 8.5-6 range. I finally used a hughes cam with these specs, after running a tp-238 (230 @.050/480) for several years ;

Camshaft Technical Details
Intake Valve Lift 1.5 .470"
Exhaust Valve Lift 1.5 .506"
Intake Duration at .050" 215°
Exhaust Duration at .050" 223°
Lobe Separation Angle 112º
Intake Opening at .050" -1.5° BTC
Exhaust Opening at .050" 46.5° BBC
Intake Closing at .050" 36.5° ABC
Exhaust Closing at .050" -3.5° ATC

Cranking compression was 150 or so, with the second cam. Runs just fine on 87, total mechanical advance of about 34-6%.

Whoops, I didn't mean spendy in the 80's, I meant crappy!
