what solid cam is equivalent to a hyd 268 ?

It is your car, and I understand, having done the same with my 66 Cuda. It is as stock Formula S Commando as I could make it, except I run an early A Hurst instead of the Inland shifter and a better clutch. I'd run a windage tray and a high pressure oil pump spring if you didn't in the last engine.
this 273 that blew up did have a vintage tray on it already . the oil pump I : have a question on though ,is when idleing at 800 rpm with the valve covers off the oil is squirting like you cut a main artery on your body. I never see oil squirt like that on any mopar engine . just wondering if it had a high pressure instead of a high Volume oil pump installed previously. any way to tell? numbers on the oil pump somewhere? one more thing , the rocker shafts have the grooves cut into them for more oiling .
