Cam question

[Louisianimal]

Thanks for all the info and responses.

After you buy cams, adjustable sprockets, and heavy duty springs the tools don't seem like much at all.

I used a file on the OEM sprockets and ARP bolts instead of adjustable sprockets. The adjustable sprockets would have probably saved me some time.

I've been thinking about putting my cams back in. If I do then I'm going straight to hex adjust. The simple cloyes adjustable gears stumped me into a big headache.. I just want my sound back, really don't give a hoot about more power, but I do want them properly set up this time.

A file? What kind of file cuts hardened steel?
I have cut many modular Ford keyways, not a single one would cut with a file.
They are hardened and need an angle grinder or similar.

Maybe you have special files?

Diamond file cuts hardened steel, but they are small and usually are rated in microns..I have some in my toolboxes at work.

Would this kit work?

Yes, I have diamond files too. They are small and would take days to cut even a 1/32 off of an induction hardened cam gear.

Try it for yourself if you think I am FOS.

I'm just glad that the days of grinding keyways are over! Thankfully there are adjustable gears now that take care of all that. It used to take days or weeks to degree cams properly by the old method. Now I can do a 4v in a couple hours.

I was agreeing, diamond files are for small, micron removal of material..I use them in moldmaking/repairs..I laser weld imperfections in injection mold features with .007 -.012 diameter wire and often use diamond file to bring it back to original.

Will it work? Theoretically yes. But with a 9" wheel (tiny) and probably Chinese dial indicator, etc. I wouldn't trust the readings.

I went the cheap route at first, set everything up and could not get accurate, repeatable readings. Drove me crazy.
Once I got some quality stuff like Starrett dial indicator and proper 18" degree wheel, then things turned around completely and now I get accurate, repeatable results.
Also the modulars require more than that kit, you will need a solid adjustable lash adjuster so you can set zero lash, I bought mine from modularspeed.com a million years ago. It is a follower with the oil hole drilled bigger so that a small screwdriver can be placed inside to elevate the lash adjuster. Proper crank socket is a must, as well. A piston stop is necessary to find TDC, I use the valve compressor tools also. Cam lock tools are handy for the OEM cams, the aftermarket stuff not so much. I actually made a tool for the Bullet cams in my buddy's drag car, he took the measurements and I made the tool. It worked great hahaha!

Pic of solid adjustable lash adjuster/follower with enlarged hole I bought from modularspeed.com a million years ago:



If you look up modular speed now, it brings you to the MMR website, which is incredibly ironic, since MMR stole some of their stuff from modularspeed. I am not a fan of MMR, their products are needlessly expensive and like I mentioned, the blatant stealing of ideas,but I digress.
Here's a pic of that custom cam tool we made


BTW those valve springs were killer OMFG
And people wonder why I remove the followers lol

Wow, that is some close tolerance work. Definitely way beyond anything I am doing, good for you!

Sorry to the OP for thread hijacking

pic of welding back of 1 of 16 insert blocks as this one was easier to grind the front and weld the back and grind to size then try to repair the front. still had to maintain size of block. The small wire by pencil is 0.012 welding wire. It is all done thru microscope. You don't weld large areas with laser and this block is too small for tig as it would make it too hot since it is so small.

These folks know what they are talking about. I went the cheap route and made it work. I had read a large degree wheel was a must so I PRINTED a large one and done. The HF dial indicator served me perfectly well. If you go this route buy the one with the vice grip (Did I mention I have one and I am willing to sell it). I also bought a SOLID lash adjuster. (I can sell if interested). I didn't use a piston stop. I used the dial indicator and a long attachment to get into the valve to measure Top Dead Center (If you do this measure it both ways). Some auto-parts stores will let you borrow a spring compression tool. Last, I didn't use a crank socket. A crank socket would have been nice, but I made it work without one. I was able to get repeatable results.

These adjustable gears will cost about $170, depending on how far you are adjusting. I used:
2 ea CLO-P9139 Cloyes Shaft keys
2 ea CLO-S790HP9 Cloyes Gear - Cloyes Timing Camshaft Sprockets
1 ea TFS-51800505 Trickflow Specialties TFS Adjustable Crank Sprocket

If my notes are correct, I ended up with an Intake Centerline at 113 and the Exhaust Centerline at 112. Intake Duration is 204. I wasn't going for 'sound', but rather slightly improved performance since I planned to supercharge.

I took me more than a couple of days because I was learning everything and I was enjoying taking my time and doing things right. My engine was out of the car so it was easy to do the work.

Intake @ 113 and exhaust @ 112?

Not much of a change, stock is 114/114
