I use the Lingenfelter 74219 cam. It was designed specifically for the Superram.

I've always heard too that superrams don't like split duration cams and that's why the lingenfelter cams for it aren't split.

The LPE "219" cam was designed to be used in conjunction with a SR and LPE's vette heads on their crate engines.Their vette heads have a smoking exhaust port so the cam doesn't need a larger exhaust lobe.You will probably need a dual pattern because stock Sportsman's have weak exhaust port numbers.

IM running the 213 LPE cam in my 406. Its designed for 383-406 sb chevys inconjuction with the SuperRam. Just FYI The 219 cam isnt the only one designed for this intake. The 213 has 224*-234* of split duration. I havent installed the motor yet so I cant say how it performs.

Something in the low 220s is right on target with the combo you are building IMO.

I've done a ton of comparisons on my engine analyzer, and for overall performance, you can't beat the LPE 219 cam. I've got one that I am putting in my 383 next month. Of all the cams I tested, the CC306 made about 10-15 more hp than the 219, but the 219 had a higher avg torque and hp curve of all the cams.

With your Dart's, I'd get some port work done on them. They seem to have a pretty weak exhaust port, and bad intake/exhaust ratio. If you run them stock, you are probably better off with a split duration cam, although the 219 will work. I'd go with the CC306 or the 219, with the CC304 or ZZ409 cams being close behind.
