Cam is ground with the intake and exhaust lobes switched.

Well.... that didn't take long......ha

Back in the day some dirt track guys tried that. I remember seeing a magazine artice. I also read about them reversing the rotation on a sbc dirt car to help keep the inside tire planted better.
I'd almost bet there were marine application engines that ran reverse. I know there were quite a few of the reverse rotation 427 Fords from boats. They would have been mounted dual with one engine rotating the right way.

the marine chevy version of the 454 also did the reverse rotation in boats, the 454 boat motor l got for the hauler project l had to make sure it was a standard rotation one, l do not know if the reverse ones work with the 7OOr4 and other chevy trans.

Not to be negative or anything, but this setup definitely needs some really good air filters. Maybe even mud guards on the intake. I like the intake configuration a lot better than the exhaust, but if Cadillac could do it in the 30s, no reason not to go for it. Personally, I think snaking the exhaust over the back of the engine would look better. But that's just me. Its still fun.

I've seen the reverse flow V8 before in an old rod mag from the 60's or early 70's - definitely wild looking but a performance dud due to now having smaller intake valves and ports than the exhausts...Here's a pic of a Nailhead done the same way

Yeah, I read they didn't work out that well either due to port and valve sizes but what fun it was back in the day when people were wildcatting design ideas. I saw an early Micky Thompson twin engine dragster with a flathead and a SBC IIrc. We just don't see fun stuff like that at the drags anymore.

wouldnt they have 4 (or 5) dazzling speeds in reverse?

Flip the axle? skull? dmw?

The ole Ford banjo rears could be installed either way.

Straight cut gears?

A special ground cam so the profile is reversed but the motor still turns the correct direction may be one way to do this.

Here's how the BB Chev is done -
two gears, no chain, so the cam itself is actually running in reverse too.

yea, easy to flip the axle. And a lot of those old champ cars and sprint cars didn't have a transmission, just an in and out box, got pushed off to start.

Looks like he used the wood to hide a bad welding job on the top chop.
