I'm thinking the RPM Manifold will be a better match for the smallish cam for your CID your using and the parts you have.

I consulted Comp Cams (more than once) on the cam selection. I posed the same question to them, but they said that with my heads and set-up, the peak power should still be right at 6000. They pointed to the many articles where the Comp Cams XE282 (232/240@ .050 565/574 lift) was used in 393's and 408's with 185cc heads and similar compression that made over 500 HP on the dyno at just under 6000rpm with a lot of torque using a Victor Jr. intake. They said that my cam (236/242 @ .050 555/576 lift) is one step up from that one which should work well since my stroker is basically one step bigger than the 408. Also, they said that with my 2800 stall converter and 3.55 gears, I shouldn't go any bigger. Other companies I called actually recommended smaller cams with less duration around 230/236 @ .050.
