Isky or Potvin
Did the late Jazzy Nelson use a Isky or Potvin cam in his FH powered car. I do know it was pretty fast for it time. The Bean bandits used to respect it.

Re: Isky or Potvin
Does the 505 represent the lift as the 404 did?

Re: Isky or Potvin
That's amazing. I never heard of that cam before. I wonder if Tom Beaty(sp) was aware of it or maybe it was not a good cam for the salt flats.

I talked to Tom many times at Bonneville but we never discussed cams. I am sure he was aware of it. It would work very well at Bonneville. |

Re: Isky or Potvin
Have you ever tried to grind a 505A or would it be impossible to do without a core to start with?

Re: Isky or Potvin
Pete, what kind of springs do you use for that? Is this a roller cam?

Re: Isky or Potvin
505 lift. I take it you need a billet cam with no cam bearings in the block? Or you modify the block for that much lift?

Re: Isky or Potvin
And here are some pictures of the 505A that Pete is talking about - with some side-by-side shots against the 404A.
I have yet to run the cam, need to build a very "special" engine for it. 505-A-lowres.jpg 505-404-Fronts-lowres.jpg 505-404-TopBottom-lowres.jpg And Jazzy Nelson's Coupe . . . probably the fastest drag coupe that ever ran a flathead. Jazzy ran the 404A quite a bit, but "wanted something bigger - and a secret grind" - that is when Ed made the 505 for him. JazzyNelsonFiatCoupe.jpg |
