    I sure am posting a lot latly, must be something to do with the below zero temp. and no heat in the garage, anyways, The angle I am refering to is when it is mounted in the frame, and it has that "broke body" look. Unlike when an original engine is in a frame (usually) say like a SBC, the engine is tilted to the rear, and the intake is actually made with the carb base at a forward angle so the the carb is actually level. This leads to the float bowls being level, air cleaner, and the oil pan having the sump in the rear always submerged, But what about some of the drastic angled mounted motors in some of the "wilder" looking rods, the only name I can think of would be like the "Purple People Eater". How is the carburation affected on a set up like that? Also what are the effects on the driveline? Do you just have a crazy upwards angle on the rearend? I like this look, but am unsure of the principles, seems like most of these configurations have the motor mounts rising around 3-4 inches above the top of the frame. Any thoughts on this, or am I on my own here?...Ken

    If the driveline angles get too crazy, u-joints are going to start going left and right, along with vibration problems. CV's are used to cure that, but that means getting a new driveshaft made. As for the carbueration, no idea.
    Now that I think about it, I'm not sure if the PPE was a fully functional machine - anyone know as to whether or not it was an actual running, reliable motor?

    I try to keep a 3degree angle on my engines and transmissions no matter how high above the frame i need it to be, for an example, building a 37 ford truck with a frame ride hiegth of 5 1/2 inches, with a 30.5 inch tall rear tire, the bottom of the rear yoke is 3/4 inches above the center section of the frame, I have to raise the engine up in the frame several inches but I keep the engine angle at 3 degrees, if you mess with the angle too much, the carb will try to die when you come to a stop because of the fuel level moving forward and cavitating the jets, or too much angle and the rear jets will loose fuel under acceleration, hope this helps some

    Does that 3 degrees refer to the carburetor/intake or the centerline of the engine/crankshaft? Also, in your opinion, how does pinion angle come into the equation with extreme driveline angles?

    I am pretty sure PPE is functional, I actually saw it for the first time, on that show with that bone-head, (sorry, I mean Goldberg) being the MC, they had PPE "drag" down a strip, he (Gold-****) was "talking about real hot rods" anyone else know the show I'm talking about? Any how, that look is also on that "royal kustoms" rod...Cherry-doll-face & her husbands shop, over in seattle. I took a hell of a lot of pictures at Hot Rod Arama of that set up for the look (I heard it was on E-Gay) but they didn't turn out worth KRAP!!!
    I don't see much of that "broke body" look, so I am hoping I'm not falling into another "FAD" .....Ken
     
  6. They fit an angle milled spacer between the intake manifold and the underside of the carburetor.---This keeps the float chamber in the carb. level like its supposed to be.

    People get all worked up about their carb not being 100% level.......it's a bunch of nonsense....ever go 4 wheeling??? Carbs can run at a pretty steep angle.......
    The earth is not FLAT...............

    I use a 4-5 degree angle in the pinion, downward, to maintain a constant movement in the runion caps so the bearings in the u-joints keep rolling and moving, the 3degree angle is crankshaft...the angle in the pinion also gives good bite in the rear when playing hard with the noise peddle
