Thread: How do these guys reverse the intake and exhaust?

Tweet

Ive seen a few pics of V8's with the exhaust and intake reversed to the intake goes into the exhaust ports, and the exhaust exits out of the intake ports. I was wondering if theres a website I can look at to see how these guys do that. Thank you

It's all in the cam.

They just change the cam grind so that the exhaust valve opens on the intake stroke, and the intake valve opens on the exhaust stroke.

It's not very efficient without major head work, because exhaust valves are much smaller than intake valves. I can't see any reason for it except for visual impact.

Looks like forced induction valve size may work in there favor there. Looks like old Buick

What an interesting combination! Looks like a nailhead Buick with a crank driven blower with 4 carbs, pushing air into what used to be the exhaust ports and blowing out of the intake ports. Obviously some folks trying to think outside the box! Must not have worked too well or we would be seeing a bunch of them. Certainly does keep the profile down though.

Looks like one more mod to put on the "why bother" list. Sure would be a bunch of money spent just to slow the car down!!!!!

Don't forget this was done at a time when everyone was trying new ideas in the need for speed.I give the guy who did this applause for trying something new,"different".He found out it wasn't so great,but at least he tried.These guys during this time did EVERYTHING you could possibly do with a engine,except for mount the engine,or engines upside down.Most were flops ,but had to be tried.

There seems to be a number of people who have done this do a search on Google I was surprised

this was done on a flathead ford for the flatfire streamliner about 5 years ago . as one stated with a forcedinduction setup it would eliminate the need for major headwork , BUT i see a major down fall in the heat of the new intake area being in the major heat area of the motor . supercharged=heat,intake in the block= major heat .....
