  1. The belt load on an R2 from the blower belts is very high and will result in low life compared to an R1. Of course many of us have seen a non Avanti pump used on an R2 Avanti and then due to longer distance from the pulley to the front bearing the shaft fatigues, breaks chews up the radiator and breaks the shroud or something like that!

    On the water pumps the shaft forms the inner race for the ball bearings and has a groove in it and that is where it breaks.

  2. I will agree that they had Avanti influenced styling but to call them Avanti sedans is not fair to an Avanti in my opinion. These cars were very very very cheap looking on the inside and the styling wasn't very clean. Just my opinion but I hate to see them called Avanti sedans!

  3. I have a cast iron R3 manifold.

    In fact the R3 heads were really designed for the larger bore engine that would have come out in 1965 and would have used the R3 heads, cast iron R3 intake and the R3 exhaust manifolds. In fact there are R3 exhaust manifolds with the mounting bracket for the alternator as used on Hawks and Larks. The larger engine at 340 cu in would have been good for something like 310 hp.

  4. Stiffer rear will increase over steer or decrease understeer depending on the car. Stiffer front will do opposite. So in general you have to balance the spring rates. But you will have to experiment to determine what works on your car.

  5. Well that is one of the things that Altman messed up! I think part of the problem they faced was the way the SBC engine fits in the car. There is vary little clearance to the hood even with the front of the body raised compared to the Studebaker.

  6. This is just speculation but educated speculation. A 340 cu in Studebaker would most likely have better low end torque than either an R2 or R3. Being that the heads would have been the same as the R3 heads the maximum horsepower would have been more than an R2 but less than an R3. So it would have felt strong off the line.

    The 400 cu in SBC in the Avanti IIs had bad heads and cams. They ran ok to about 4000 rpm and then fell very flat. If you have an original it needs better heads and a different cam to wake it up.
