Has anyone had experience or heard anything about them?? I've heard bad things about Fidanza's product, but couldn't find much info on the Comps'.

Any thoughts?

Thanks,

I think I read somewhere that Fidanza made them for Comp. You can get the Fidanza gears anodized red, blue, or clear too. I sent the set I bought back to Summit after I read about the carnage they had caused. I think I'm just going to see if one of the sets of stock gears I have laying around gets the timing close, and then maybe grind the key on the gear a bit to make it right. I already bought a set of ARP cam gear bolts ($$$) so I can try it as many times as needed.

Ok, so being that comp = fidanza, and I don't trust the surface area of those screws to hold the two sections of my gear togeather, I'm going to have to go some other route.

I've read that the keyway is not (supposed to be) load bearing, and the cam bolts are what holds the gear on. Does anyone have reason to disagree with that?

So logically, I'm going to either have to do this myself, or find someone close to me that has the tools to degree these cams. Correct me if I'm wrong, but once I find how far off (in either direction) cams are, I could file down the corresponding side of the keyway until the cam can sit at the propper angle. With that done, I would think it would be good to have something take up the remaining space on the other side of the keyway where the cam key used to sit. Can I just have a machine shop weld there, and grind/sand it down until it is flush with the gear? or would I be wasting my time?

Any ideas would be greatly appreciated. Otherwise I'll be scrapping this build plan, and going with something else next year.

Thanks,
-Ryan

I was considering HiTech's stage 2 PI N/A cams.

I'm not putting any cams in my engine without degreeing them though, sorry. I'm a firm believer that you need to do stuff the correct way, or not at all.

I have heard of a lot of people who have ground down the key to move the gear more on the camshaft. This is the way I now plan on doing mine.

If you really want adjustable cam gears, you can go to http://www.lmengines.com/ . I think the ones they make are fairly expensive though($400 plus maybe? not exactly sure). You might also try sending Johnny Langton a PM; I think he had a deal with a local machinist who modified some stock gears to be adjustable. I'm not sure what the status on that is, or if they are even still doing it.

if you run the 262AH on say a PI motor.....ordering with or without the 5* advance wont set you very far out of an acceptable range.

Cam gear keyway mod

You can use the stock gears and modify them, only issue is some gears are very hard and thus are difficult to machine but it can be done... To use stock gears set them up as usual, see what the timing is, and figure out which way you need to move the cams. Then remove the cam drive, file/grind on the side of the cam gear key you need to in order to move the cam the proper way, and re-assemble to check timing... repeat as necessary... Cobra R's ran NO keys in the cam gears so the bolt takes all the load once it's properly torqued... To do this you need to be be able to take all the slack out of the cam drive so the timing is checked correctly....
