The distributor center shaft size of .530 should be the same for all the years of the 240 or 300 sixes as well as most all other Ford OHV Engines from sometime in the 1950's on up.

I guess I'll have to order a melonized gear for an engine using the same shaft size and see what's different or the same from a 300? It doesn't make sense they would make a totally different gear just for those 2 engines....
I believe the 240/300 uses a 16 tooth gear while most other engines use a 15 or less tooth count.
I have been looking for the cam synchronizer from the 5.0L explorer engine to verify that. Why couldn't the cam manufacturer change the drive gear count on the cam to match a 351W? They both have .531 shaft size. I need to get the O.D. of the 351w gear. Should be the same as the 302? I know the I.D. is smaller on the distributors I have had.
I'm sure they can and especially if the OD of the gears are the same.
Talk with John Partridge at Bullet Cams.
what intake is this thanksIf you have an old fence post, a drill press and a 17/32" reamer, you can do it yourself.
I used the original EFI fuel rail and just bent the injector cups to square them up.

I just hear about comp cams new flat tappet lifters.
Diamond-Like-Carbon (DLC) coating for lifters
https://egnation.com/2023/01/24/dlc-lifters-provide-flat-tappet-protection/
This may be a solution for the lifter failure problems? Has anyone have any experience or knowledge about this?
I really want a roller cam but since no one sells a steel gear or give me the contact info of who actually makes them I guess ill have to settle for a flat tappet cam

tmc5150 I just called bullet because I got a hydraulic roller cam from them and at least on mine I cannot use a melanized steel gear has to be bronze or composite but they did say for an upcharge they could make it to where you could use a regular iron gear.

The DLC lifters seem a valid idea. A buddy has it done on some internal bits of high end roadrace bikes, swears by it. I wonder if the distributor gear is a good candidate?

They said they could make a billet roller cam that would work with the stock iron distributor gear? I wonder how that is but I'm interested if they actually can get the two to work

WesP95, when I spoke to the person earlier we were talking about my camshaft that I bought from them and when I asked him if somebody else wanted to buy it would they be able to get it to be able to use an iron gear and he said for an upcharge. Now maybe he wasn't thinking about the cam I had, although he had the serial number. I thought it was strange too and I would always double check first
I called them a few weeks ago and they went over the different materials a roller cam could be made of and was very clear that a bronze or composite gear was my ONLY choice! I finally got him to tell me who made the OEM steel gears. Morel is the company. I tried to call them with no luck. I did find a company that sells their products. He told me he can get a cast gear of some alloy that can be run on 8620 and 9310 cams. He said that they make a bronze gear that is made of a very hard mixture compared to the other crap comp and others are selling. He said you can run high volume oil pump with them and he knows engines with well over 30k on them.
Here is a linkto their Facebook.

I want a cam for my 300 that has an choppy idle like the 268 comp hydraulic cam. Does anyone know someone that has the solid roller cam in there 300? I'm curious what they idle like and the specs? I need to find a cutter(like they use to cut down valve guides) to cut down the cover bosses. I'm gonna use studs and make spacers to bring it back to original height. Any Machinists in here that point out what it's called and where to buy them?
In order to keep the oil holes/ groves in the lifters in the bore I am sure I'll have to use 1.7ish rocker arms to get around .550 lift.

Hi tmc5150, I bought some Perfect Circle Valve Guide Cutters back in the late 1960's and I still have them (for the old PC Valve Guide Seals). Here is a link for some of the similar cutters that are available today some will also cut the Valve Guides & Spring Seats lower too, good luck on your build. https://www.summitracing.com/search/part-type/valve-guide-cutting-tools

I hope that works. I would hate to ruin the camshaft if it wasn't compatible. Also when you called bullet cams what materials did they tell you they used?
Sorry I can't remember what they said they used....I was just trying to get him to tell me who makes the OEM distributor gears and what types of metal was used for roller cams.
this is what I was writing down. He was giving me all that he knew about the compatibility of the cam and gear materials. Straub told me all about how Morel worked with Ford on the factory roller cams and gears and shortly after GM.
The lower part numbers are for the hard bronze gears depending on shaft size from Straub. The bottom was a possible quote if I wanted the Morel company to make a custom gear......iirc. He told me it would be at least 8 month wait if they would even take the time to make our gears.
Staub called me back a week later to tell me I had won the lottery because Morel still had the cast gear that was compatible with the 8620 and 9310 cam materials.
I was very appreciative that they both spent their precious time to talk to me and share this information.
