My 422 smallblock build

From my big block dyno tests I see no reason not to run the dual plane with any of the cams mentioned. With a well executed dual plane I think you will be up about 3-5% in power in your cruising range and even @ 6,000 rpm. But I am getting old and my thinkin' may not mean crap.

Too many see every engine combo through a dragstrip lense . This combo while not maximizing every last 1/4 HP will deliver what the SSG Karg is looking for . And doing it with his exhisting components . If he wants to change directions later he can always add a different cam or rockers .
