Just for everybody's info, here are the spec's on the two cams.

E303 - 282/282 degrees adv., 220/220 degrees @ 0.050, .498/.498 lift, 110 LSA.

F303 - 288/288 degrees adv., 226/226 degrees @ 0.050, .512/.512 lift, 114 LSA.

I like the tighter lobe separation angle of the E303, but your compression ratio is begging for more duration which makes me lean to the F303. The nitrous shot might like the wider LSA of the F303 better, too.

In my opinion, keep the motor carbureted and use the F303.
