    I used to think it was cool when I was a little kid then when I got older I learned that they really didn't run much better breathing through the exhaust ports. The Ol' Man told me that it made it easier to run stack injection or multiple carbs, or in certain applications like race boats or some rear engine cars it was a better setup logistically.

    But it does look cool. ;)

    Yes, something like that, but it's been several decades and I have no pictures of it, so my memory is hazy. I really didn't know much about what I was looking at, at the time, but I know I recognized that it was set up backwards, with the intake going in at the sides of the block and the exhaust coming out at the top, and that's what started the conversation about it to begin with, then the guys telling us about it said that it did just that, that it drew thru the old exhaust ports and exhausted through the intake ports.

    But I can't recall if the carbs were mounted down low, or if it used carbs mounted on top that flowed through a manifold down to the sides of the block. It did not have a roots blower sitting on top, because that's where the exhaust pipes were.

    Exactly. Neither did the Smith Jiggler where the exhaust went overhead in air cooled heads for a little improvement at a lot of cost.

    Henry’s flathead exhaust was in effect a fire tube boiler, running intake reversed through it is an impediment to breathing.

    Cadillac got it right.

  5. In 1991, or 1992, my sons and I went to the nostalgia drags at Sacramento Drag-strip. John Bradley, who at the time had the worlds fastest flathead. was running a set-up like that..

    If you look at the picture (post #8)you can see that it is John Bradley's car. In around 58 or 59 I went to Half Moon Bay drags to see the Gene's Brake Spl. John Bradley and his "Worlds Fastest Flathead" He won Top Eliminator running in the 9s at 150 or so. In the 80s I was in line at El Mirage and noticed the lakester behind me Flathead powered. It was John. I told him I saw him at HMB and we talked for a while. Nice guy.

    This is what Jimmy Stevens does to flatheads these days. More effective 52979921_2123601184372363_5622706759966654464_o.jpg than swapping ports

  8. Ok so it may have started out as a flathead and while not running in reverse the intake and exhaust are on both sides.
