I realize the best way to go would be to get a new Stipe cam, but what is the downside to one of the regrinds all of the parts sellers offer?. Which is the best choice for a cam gear? Aluminum? Nylon? Bronze?
I once had an unhappy experience with a nylon timing gear, so I'd go with bronze or original Ford. Others will say any of those is good. And some will say nylon because it's quiet. Yeah, it gets REAL quiet when it fails.
The major downside to any regrind is you have to buy adjustable tappets. That is $80 more if you don't already have them installed. Also it is a good idea to build a thrust washer to remove end play when you use a regrind. 26-7 cam cores are less prone to having an end play catastrophe, but even when you have to buy cam and tappets it is still less expensive than a Stipe. I don't know why a regrind isn't considered as good a choice as a stipe. I have used a nylon gear and love it. I run a radical cam profile and haven't had any problems. I have seen the nylon gears fail. I have also ran aluminum and like them, but I dislike the noise they make. I also have had an aluminum gear fail. If you purchase a radical cam profile stay away from the cast aluminum cam gears.
I'm exploring my options. I have a tired '27 engine in my '21 I put in because it runs. I have not a clue what I will find when I open the '21 engine I have, expect to get into it this spring. Between the 2 engines I do expect one will get a total rebuild in the next year or so, aluminum pistons, some kind of cam, and all of the other paraphernalia it will require to be dependable and fun on local tours. I want to be able to drive the car 100 miles in a day, and have a little extra performance to keep up.
I am running a cam reground by Norfleet in Dallas. It performs well. Their price to regrind a cam was about $20 ten years ago, likely a touch higher now.
Why don't you give them a call?

There are some really bad grinds out there.
The cam is the lungs of your engine.
Save up your money and get a Stipe.
There is a difference between something running good, and something running the best for the dollar difference!
Steve - I thought your 'bad experience" was with a fiber timing gear,......??? I remember that one because of the great photos you posted. So, you had a bad experience with a fiber gear "AND" and nylon gear? I never heard about the nylon gear problem you had. (???) I always thought the nylon was not as tough as any metal gear (aluminum, bronze or steel) but much better than a fiber gear. Just wondering,........harold
The nylon adventure was with a Suburban. It died on I-25 in Colorado. Quite a mess with plenty of damage. Spent a week in Trinidad waiting for parts and repairs.
Nobody has mentioned the generator here. That's a source of strain and wear on the gear.
I had Joe Bell rebuild my engine a couple of years ago with a Stipe 280. It is in 27 tudor with a holly vaperizor and I have run 47mph with this car. I think that's good.
I like the 280 but if your going to make it breath a little better with the B exhaust and A carb the 290 really turns it on.
Check out the Carnegie Brothers, Ford 'n Moore, Spokane, WA. http://www.antiqueautoranch.com/fordnmore/
They know how to regrind and advance a camshaft so the T can both pull uphill and run good on the flat. Read this thread: http://www.mtfca.com/discus/messages/179374/242215.html?1320565384

Whew! I just read through that 2011 cam discussion from the link above, and I'm worn out!
