Cam Degree wheel needed
Anyone have one they want to sell? Or any recommendation's on a cheaper one to buy? the summit reviews are all over the map from great to crap. I just used a small one but i had to rig it up so much i dont really trust it. My cam did come in at 110.05 as opposed to the 110. the cam card showed. im going to have to do this again since i also am in the market for a new timing chain after realizing it has too much slop. yes a rollmaster 30k miles on it. (hard miles) Thanks as always.

I have a Comp/Powerhouse crank socket and a Comp degree wheel that works good for me.
https://www.compcams.com/ford-buick-...ocket-cpg.html https://www.compcams.com/sportsman-d...l-7-5-cpg.html You just need something like a dial indicator or "bridge" to find TDC If you are chasing a 0.5 degree good luck! there is probably even on a new chain enough slack for that. The bigger diameter wheel the more accurate you are

I always print a big one and stiffen it with some backing.

i just bought the 2 links skip posted. Thanks! I have the dial indicators and made a heads off piston stop. i think my 1/2 a degree off is im hearing that using a dial indicator for tdc is not the ideal way. either way it was/is a fun learning experience.

Also the crank socket will fit in the timing cover seal if you are just checking a few things like V-P on an assembled motor.
I leave the wheel bolted to the socket. Have an extra one for SBC/409 cranks with a wheel on it too.

How is everyone offsetting the cam timing these days ? I still have a Mopar offset key kit P/N 4286500 in my tool box, which I used when I setup my roller cam last year.
Checked/rechecked mine a bunch of time, and was about half of a degree off. Offset keys in kit: Color code for cam keys: Natural-1 Degree, Red-2 Degree, Blue-3 Degree, Yellow-4 Degree, White-5 Degree. |

I have the large diameter blue wheel from moroso and it worked great for me. Not cost prohibitive either imo.

My last cam degree came in spot on, new Scat forged crank, new Comp cams cam, new Cloyes timing set.
Checked every aspect along the way 3 different times for sanity |

I like the cam keys myself. Crank sprockets are never right on, plus you have to reset the TDC marker on the wheel.

https://www.holley.com/search/?q=Cam...and%20Bushings There seems to be a limited selection there. Possibly you could use a combination of a cam key and/or a crank key and/or the bushings to get where you need to be There are limited possibilities on ebay that are out there as previously mentioned

Has anyone ever checked the cam timing after 1K, 5K or 10K? I wonder if it changed much? Depends on the quality of the chain. My theory is to advance it 2 degrees, to allow for stretch and break in. Am I wrong?

I would set it where it should be and just check it every so often. Then you can keep an eye on what it's doing. When were at the track, that's the first thing we do before our first run, check timing. On the street, couple of times in the summer. I find the timing bounces around a bit on the balancer with a stand alone distributor. With the use of a crank trigger timing is solid on the balancer when checking. Seeing this is the street section, you maybe running a vacuum advance to add timing at cruise. So you have Initial, Mechanical, and Vacuum advance. I wouldn't worry much about 2* as I would make sure you timing is working properly through your driving season.

Loosing two degrees of timing if your motor is Cam’ed to the point of having a idle that’s at the edge of being stable when warmed up can mean a lot!
Slap one head on and make a cranking compression test between the two settings and you might find yourself thinking twice.
