228 intake duration at 50 lift? No way is this a truck cam. It's the predecessor to the 761 cam that Mopar Performance used a thousand years ago to make around 400 hp with a 318 with their ported 302 heads. The 757 cam is much easier to live with.

I think I'd look at Lunati's smallest or second smallest Voodoo or a Hughes with around 208 intake duration at 50.

The really sick part is that when this camshaft was being sold, Direct Connection/Mopar Performance refused to publish any figures for duration at 50 lift. Reading the engine manual at the time it sounded like they thought the public was too stupid to use the information properly. Their suggestion was to pick the cam by the lift, and they'd tell us what lift to use to get what results. There was a series of recipes in the old engine books, for example, how to build a 13.50 machine, something like that.
