302 e 303 cam / dist gear

Not sure where to post this , excuse me if this is the wrong spot , put an e303 cam in my 302 and not sure if I can run my dist , it has a performance world 6002 dist / hei conversion , not sure what kinda gear it has , tried a search but it is unclear , some say you can run a stock gear with a Motorsport cam , not sure if it's cast or steel , can anyone shed some light on this

 

Steel cam requires steel or bronze gear... Seen a iron gear eaten by a stock HO cam and the E will be no different...

I suspect "stock" refers to the gears that are on the factory TFI distributors...

 

You can`t use cast gears on roller cams.

 

I tried to install the Ford Motorsports steel gear on the Boss 302 dual point distributor I used in my 71 Comet with a F-303 cam. Ruined the distributor shaft as the interference fit was so tight I couldn't get it on and aligned. Researched a bit and purchased Summit Racing MMA-29418 steel gear priced at $39.97 which was a lot cheaper than the Ford gear and easy to install. You had to heat slightly and then drill for the larger pin supplied. You will have to use a press to get the old gear off first.

Other option is to get a Duraspark dizzy for an 85 Mustang GT. That is what I run with my E303.

 

And it has a steel gear?

 

Yes.

 

I believe only the 5 speed cars had the steel gear.

 

I quick searched and found the instructions for your disty here.

Clearly states that you need to replace the gear with a steel one for steel cam compatibility.

 

I believe I read that as well.

 

The carbed 5.0 '85 Stang 5-speeds were first to use a roller cam and last 5.0 to use Duraspark... Automatic used a flat tappet cam with TFI dist, this incl '84 as well... The '83 & '84 5.0 5 speed Stang were carbed and had Duraspark but used a flat tappet cam... All passenger car 5.0 from '86 on were EFI & roller cammed, so had TFI dist... the 5.0 F Series went to EFI in 85.5, but continued to use flat tappet cams into the early '90s... Blocks were roller cam ready...

 

Also says hei gears cannot be changed

 

I ordered up a dura spark 85 , 5.0 5 speed dist today , thanks everyone

 

You are aware you need an ignition module and conversion harness, right?

 

well yes and no lol. i knew i would prob have to run an msd 6al or something with a duraspark dist, which i didnt want to do ,i wasnt aware that i could use the suraspark setup completely, which is the recommeded way to go? msd is ewaasy but pricey, and bulkey, hard to make it look kinda stockish, how do i go about the duraspark complete way if its possible
?
