  1. Cummins 1931 Indy Car: Packard Chassis, Completed the entire race on one tank of fuel. The lineage to the 4BT engine is obvious.

    Cummins 1950 Indy Entry.

    Cummins 1952 entry was even more unique, employing a laydown inline 6 engine. It took complete advantage of the rules at the time that allowed a diesel to be up to 401 ci, and no limits on boost, where as gas engines were limited to 183 ci. The Cummins Special set pole by more then 4 mph over the 2nd place V12 powered Ferrari's. It was leading into the late stages of the race when the turbo inlet became fouled and plugged with rubber debris and starved the motor of air.

    I did not know that link-belt timing chains dated back to 1910.
    Also, its interesting that Curtis used one pushrod assembly to actuate both valves. And maybe only one cam lobe?
    I LEARNED SOMETHING TODAY!

    Speaking of using one cam lobe to actuate both valves, we had a Reo lawnmower that did just that.

    Wasn't that a Continental engine that drove the mower off the cam?
    I think Dean Lowe could probably tell a lot about those.
     
  10. The pushrods were arranged one inside the other, the exhaust valve rod being on the inside and the intake valve rod a tube around it

    And it looks like the intake push rod pulls down on the valve.

    There were several different V-4's built for midgets and Ron Hottel of SESCO built a four holer that used a bank of cylinders from a 283 block that was the engine of choice for several years in the seventies.

    To say that this is a rare conversion would probably be the understatement of the year.

    That is what I figured at first - sort of a desmodromic effect. But upon closer scrutiny I think there may be a secondary rocker gizmo down near the cam bore that turns the pushrod motion around, while still using the same cam lobe. Look closely and see if that is the case, no?

  19. Never cared much for Y blocks, but that Weslake conversion is a thing of beauty.

    Harry Weslake perfected the hemispherical combustion chamber?
    Hmmm, interesting. I would think the Smith Collection would have a more astute research team than that.

    As with many engineering features refinements come with age. I doubt the hemi was "perfect" after Weslake was done. And the definition of perfect has to be taken in context. Perfect for max volumetric efficiency? Perfect for Maximum HP? Perfect for emissions?

    Have you looked at a modern Mopar "hemi" head? Its far from being a dome with valves. More like a hemi in name only.

    GM X8 2-stroke engine. This was an experimental engine for an economy car that was never used, each head has two pistons, one for intake and one for exhaust. It also has a roots style supercharger

    Never saw the Soviet version, but I did ride behind a 5 cyl . Kennerer in a PT-19. Real "putt-putt).

    Gonna stuff one of those in a Friends Flat head powered '40 coupe. Just waiting on the adapter from J.C. Whitney, it's on back order.

    Old Harry might have perfected the Hemi, but he sure didn’t invent it. About 15 years ago my Dad and I went to the largest antique farm tractor auction ever, in Montana. Not to buy, just to look.
    I found a 1904 Farm tractor that had: Hemi heads, roller rockers, Roller lifters,dual carburetors, rack and pinion steering, posi-track, and a blower on it! My Dad laughed at my amazement, he told me that “ hot rodders” have not thought of anything new! They just applied to different things and in different ways.
    Sometimes you just got to see it for yourself!
