    Suggestion - - - Don't use the 1/4 speed cam. Hang it on the wall.
    You need a special 1/4 speed gearing to use the cam. Schaller failed at 1/4 speed cams and also Ed Iskenderian failed with 1/4 speed ISKY cams.
    Do you have the special gear drive for the cam ???

    The distributor is an oddball too. Always wondered if this concept was really that flawed or just shunned for it's being so different. I know Mickey Thompson tried them in Indy cars in 1963.

    Bus Schaller started out building hopped up Harley 45s for racing. These engines were so developed it was almost impossible to find a new way to get more HP. But he got the idea that if he slowed down the cams to 1/4 speed it would reduce friction and give a little more power. This was not too difficult as the Harley already had roller lifters. But he had to make new cams with 2 lobes and new gearing to slow them down.

    He says he got encouraging results. Not only less friction but the lifters seemed to follow the cam easier. He claimed more accurate cam timing with lighter valve springs, more HP and longer life. And this all allowed more radical cam timing than could be achieved with a conventional flat tappet design.

    Next step was to develop a Chev V8 version. Whatever the result, the advantages must not have justified the expense because the idea never caught on.

    Detroit did eventually go to roller lifters but not the double lobe cams.
