seen that at Mitchel SD but never did happen to hear it run, but it must have moved under its own power must have had to change a few of the cam profiles the guy loved exponding on his engine style the carbs bolted to the eshaust ports definately were different the liscens plate is revs-flow or something close
Possibly very simple. Run it backwards, put the ring gear in the differential on the other side....................
I'm thinking the rotation is the same, but the lobes on the special ground cam are switched. The fuel and exhaust don't care where they come from and go to, SO you just have to have the cam open the proper valve at the proper time. What you wind up with is a small intake and a large exhaust valve. Not the normal formula for a performance engine.
There is a video of it running on youtube. Sounds pretty cool. <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/8wGf90fK-kQ&hl=en&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/8wGf90fK-kQ&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object> Norton
Not disagreeing with just adding that on a naturally aspirated car yes little gain, however add a belt driven parts breaker or an exhaust driven parts breaker, different story.
And that belt driven version would have some pretty wild plumbing to get the pressure into the "intake" ports. So to make people ask "why" even more you could put a supercharger on each side of the motor.....
This was done to flathead Ford V8s as well. A little better results since all Flathead valves are the same size.
it may be a bit rat-roddy as far as the weirdness is concerned, but i think it is somewhat traditional. weren't they doing this in the 60's? i have seen this done to bangers before so that you have 4 intake ports and 2 exhaust. i am pretty sure the old crow used to run reverse flow.
wouldn't the shape and size of the ports be backwards as well? I know Ford used a similar configuration for Indy, but the motor was designed around it, not just get attention at a car show . . . it allowed for easier 180 degree headers and note that the intake port is in the centre of the head, not the other side Someone stuck a couple of them together in a FED as well . . .
I was a little more curious about the flathead dizzy in the FRONT of a SBC. What gives? That's a lot of work to make a common engine look different.
I love it. I dont like the pipes though. I wish they could make a sharp turn right out of the manifold and flow over and back down the side of the body, sort of like lakes? That would be cool
Now THAT is the quote of the day!! I remember reading somewhere that round-y-round racers experimented with reverse rotating motors and this was an off soot to the idea? Doc.
Most cams are symmetrical. So all you really need to do is use a gear drive without an ideler gear so that the cam turns backwards. Your old intake is now the exhaust and so forth. You will need to address the distributer and oil pump. I believe these guys just wanted to look different to look different. Performance probubly was less than before.
Many circle track divisions banned the use of reverse rotating motors as it is an advantage in turning left. Not sure if the reverse induction idea came from that or not.
