Breathing new life into the 318 in the Scamp!

I'm not so sure about this cam. Seems that you were building a pretty mild motor,and that cam is over .500 lift. I would stay under .500 lift.
Did you call Hughes and give them all your cars specs ?
Or just pick that cam ?
You dont want to over cam the thing.

In the link it shows .461/.489" lift with 1.5 rockers and only 210/219* duration at .050", idle-4600 power range... that cam will be a stump-puller for sure!

EDIT: If I were you I would get a set of those lifters with the EDM holes for extra insurance against wiping a cam lobe, Hughes cams have the steepest profiles out of all the aftermarket Mopar cams. And be sure to run good oil with enough zinc in it.
