Thread: Reverse induction V8

Tweet

Has anyone ever seen a reverse induction small block chevrolet? I've seen a picture of a reverse induction on an engine on a drag but I can't remember where I saw it. I guess it's like running a blower setup but piping it through your headers and running exhaust stacks where an intake would be. What would the advantages/disadvantages of that setup be?

I've seen it done with Ford flathead V8's, probably because the exhaust system was dismal from a performance standpoint. It didn't matter how bad it was if you were using a blower and pressurizing the exhaust side of the motor and the intake ports make some pretty nice exhaust outlets. I can't see where there would be any advantage to doing it with a modern overhead valve motor, although you might tend to get some of the 429/460 guys to start leanin' your way. The weak point on those motors is the exhaust port arrangement.

bruce crower built a out side port small block chevy both ports intake Ex and intake were on the out side of the head this photo is in there 1995 crower master catalog and looks like the intake port is now the old ex hard to say how he did it a lot of furnace brazing

Good to see you back Pat

Didn't Mickey Thompson or somebody build a SBC like that for Indy back in the '70's? Had the headers up top like a Ford cammer.

crower did run indy with a down size small block 209 cid with rathman team in 1960 with the 209 chevy made 850hp but i do not think it was the reverse induction heads .there was some over head cam stuff done. mickey thompson did do some wild stuff. there is some guy that run salt flats with subaru over head cam heads on a salt flat car.with a old ford block ? flat head block? this guy run over head cam heads on a big block chevy that are off a porsche and other engines .it was on tv some time ago he was taking to dennis gauge (handle bar mustache)

thanks southerner yes i can not stop i am hooked hard i am a junky

I think this has been talked about before on here, i guess theres not really a positive reason for doing it, but i personally think it looks pretty cool

I remember articles and photographs of different people's efforts along this line, Gerald. A picture of a flathead that appeared to have four Strombergs on the exhaust manifolds was definitely interesting!

Most likely the result turned out to be not worth the effort and expense.

Speaking of unconventional approaches, and I don't intend to deflect your thread away from your inquiry, but does anybody know whether anything ever came of Bus Schaller's quarter-speed (as opposed to half-speed) camshaft concept?

At first glance this would seem to be a fine idea given the wild RPMs racing engines are turning these days.

Someplace in the big mess I call "my files" I have an article on Mr. Schaller's development efforts. The camshaft looked unique because a cam lobe had to lift the valve twice in one (cam) revolution, so one lobe had high points opposite, or 180 degrees apart, from each other.

The design must have had shortcomings, otherwise we would be running quarter-speed cams now. I wonder what those shortcomings were?

Jim

If there were any real advantages, the motors would be out there now. It's not a new concept.

Here ya go!!!If I had to guess those look like 1100 kawi carbs or honda 750 -4s

Thats so cool looking

Thats what I'm talking about. Outside the norm but cool as all heL*. I wonder what kinda HP and torque numbers come out of that thing.
