Brad,

I actually have met David a couple times through a mutual friend.

He's much more lively in person,

Something to consider is at 90 degrees after TDC through maybe 115 ATDC (depending on the stroke and rod ratio) that first cylinder is at or very near peak piston velocity so I can fully visualize how the second cylinder is getting a bit "ripped off"....this is how I interpret what's going on anyway. I may be completely 180 off...or at least 90 off, lol. So if the second pulls on the first somewhere in the cycle....as the english would say...."Fair Play to #7" lol

Again when the engine is approaching peak torque there should be a slight "ram effect" in the plenum which should minimize...or "balance" the port flows to all cylinders, so the gains are probably slight and only over a relatively small part of the powerband.

come to think of it, Mark GY3 runs one of my old street Dominators on his Stroker big block, he picked up about what I quoted on his motor...as far as I know he still runs it and seems happy with it.
