Tha Boss

I was told to get a distributor out of an 85 mustang gt with a manual transmission because it has a steel gear.Why do I need to get a distributor with the steel gear to be compatible with a roller cam and my 302 came with a roller cam. I have an 88 mustang gt(5.0 HO) and I am changing to a carburetor setup and I was wondering if someone can shed some light on this for me. Thanks

You may just want the 85 dizzy for the fact it was on a carbed car

You need the steel gear because of the roller cam. An 85 distributor was recommended because you are changing over to carb and you current distributor is a TFI (controls injector signal).
