i didnt degree my cam?

[TSTONE]

looks like the projeect is coming along great - what kind of valve covers are those?

[meissen]

Canton valve covers. I got them off ebay only to find out that Creight sells them too. So if anyone else is interested in buying them - buy from Creight!

[DETROITMUSCLE]

Hey B where did you buy that POR 15 I need some POR 20 for my headers.

[meissen]

por15.com

[DETROITMUSCLE]

damn I was looking for local, does anyone local carry the stuff?

[meissen]

I remember there was someone local at Autorama a few years ago advertising but I just ordered what I needed off por15.

[TSTONE]

did you try going to their website and looking for local suppliers?

[DETROITMUSCLE]

couldn't find any local suppliers it just has international ones, unless I'm looking in the wrong spot.

[TSTONE]

could try calling them - im sure someone has be a local dealer

Looks good B, I better have mine done before yours so i can come over and help install that motor, I might actually be warm enough to work

How can you roll the cam shaft it has a pin in it to position it to chain sprocket?

The cam has nothing to hold it in place till the timing chain is on.
It's posible and I have done it my self.

It all has to do with TDC and the relationship to the cam.
Dot 2 Dot is for reference only, it's not perfect and yes it will get you close but that is it.


If I hadn't check my last cam and just did what you guys did I would have been off 6* and that's a lot.
You want timing issues that will do it!

All I'm saying is that you have a lot of money in this and I would think that you would want it right.
Not trying to be cocky here but I have done my fare share of motors and if I was you I would want peace of mind.
Buy hey, what do I know???

I don't think anyone is trying to discredit you or say you're wrong, I just think everyone is thoroughly confused about it especially because I can't find anything about rolling a cam on any of the other forums.

Let's say the cam is in place and you have your cam at #6 TDC - verified by the fact that the heads are off (which they were in my case). We then pulled the crank sprocket off a bit so that it would allow us to get the cam sprocket in place. We made sure the crank did not move while we did this (had it pinned so it wouldn't move) and then we slipped the cam sprocket on with the dot at 6 o'clock. To get the bolts for the cam sprocket into the cam, I don't see how the cam can roll then? It would seem like if your cam rolled the slightest bit then either 1) the three bolts for the cam sprocket would not line up with the dot at 6 o'clock, or 2) the dot wouldn't be at 6 o'clock when you're done.

Edit: I did more googling and from everything I've seen they say the only way to have your cam advanced or retarded is to either 1) have it ground into the cam or 2) if you drill out the dowel hole in the cam sprocket and put an offset plug in it.

[Superman09]

Im confused as well. If your dots line up and the timing chain is on, its set. I don't see how it could change?

[JoeliusZ28]

yea i really dont understand either. Even if the cam was 6 degrees off the only option id have would be to install it a tooth off - which would probably be more than 6 degrees off. theres no way to adjust the chain, theres just dot to dot and thats it Obviously there is possibility for innaccuracy which the measuring tool will show you, but im not sure what youd be able to do about it unless you got a custom timing set or something like that.
