It's called "reverse flow" but I still am not sure exactly how it works.

Power loss probably not a concern,as it could only run a short time ,No Radiator or Water pump don't know if this runs backward or not don't think so or he would have 4 reverses and 1 forward gears withouy mods to rear,But they do make reverse rotation small blocks mine was in a cruiser boat,& most twin engine boats have 1 r=clockwise rotation and 1 counterclockwise rotation engines something about anti cavitation,

It's in the cam.. He has a rad under the truck I saw someone saying that it did have one.. Yes they make boat motors that rotate the opps way.. But this one was in the cam shaft.. There is a lot of write up about this motor all over the web..

I had to do a "shout out" to my brother on the motor. Yes it's just the cam that is different making the valves open at the proper time swapping the valves use. He was saying what they often did was run a blower on this type of motor because the first thing I asked was why in the world would you do this when you want the intake valve bigger than the exhaust? He said that this works perfect with a blower because it enlarges your "exhaust" valve being it changes your larger intake valve into an exhaust valve and then with the blower the smaller exhaust valves which become intake valves work just fine because the fuel and air are being pushed into the motor thru them with the blower.

Yep, interesting. Everything has been tried once, it's called hotrodding. Some found this useful and there have been some competitive cars over the years with this arrangement.

Seems to me that a batch of Fords from the early 60's were built for specific races that had a bunch of side draft carbs on the "outboard" sides of the heads and "bag of snakes" headers exiting from the center sides of the heads. Indy and (possibly) LeMans (GT40) racers come to mind......

What I planned on doing on my c-cab was build a tunnel ram type cross ram and run 8 side draft carbs,, Something wild and different,, But I been having this picture for a while and thought that would sure be cool and different... So for now it's up in the air..

It was the 1964 Ford Indy DOHC engines I was thinking of. A brace of Webers feeding the intake BETWEEN the exhaust and intake cams on each bank,and the exhaust coming out from the center of the engine in a convoluted "bag of snakes" and exiting straight back through the middle of the car. Really wild design!

I believe I saw that very engine run at the Hunnert Car Pileup in Morris, IL. a few years back. Weird, cool and impressive!

The reverse flow would only need a cam. Just opens the exhaust valve on the intake stroke and the intake on exhaust. Still turns the same direction.
