Can I use it on my old distributor?
That's good info there. I was under the impression that any roller cam required a steel or melonized distributor gear. I learned something new today, so thanks for that.Since it looks like you're putting in a aftermarket roller cam, they're typically SADI. They're cast ductile iron where only the lobes are hardened. They can use a regular cast iron distributor gear.
When I was doing my GT40P swap a little confused on this I did some investigating. I called a tech from Ford Motorsport, a tech at MSD and a tech at Howard's Cam. All three said the same when I asked specific questions at to types of cam material. Howard's will tell you they use SADI cores and that you can use either a regular cast iron or Melonized gear. Howard's told me there's something like 3 companies that make them and that all the cam companies buy from these three. As far as Comp Cams, their cams are SADI and to use a Melonized gear only. I've read on line topics where Comp Cams head engineer Bill Godbold said you could use a cast iron gear in one article and in another said you couldn't. I've read on other forum where one tech at Comp said you could run a cast iron gear and another said you couldn't on a SADI. Crane says you can run a cast iron gear on a SADI and they're owned by Comp Cams. I read one article where MSD said they use a Melonized gear as their default gear as it will work on a flat tappet cam, SADI, or Ford factory 5150 billet steel.That's good info there.
