Gastrick....what would you knowing how to drive a train have to do with knowing how a engine works......
Really though, you get the prize!
That's all it boils down to, camshaft timing.
Rotation has nothing to do with it.
This was used years ago on some Flathead, nailhead, and a few other engines that had close to same size exhaust and intake valves. Someone saw that the exhaust ports had as good flow as the intakes.
These engines made more torque and h.p. that way.
That small Chev. pictured looks cool, but would be a stinker from a power standpoint. Very poor exhaust flow will be the reason. Poor velocity.
I was trying to give some hints on page one, but no one bit.
If anyone wants to build one, I know an awesome cam designer.
