quick question. why use a cam tool to degree it. can your just use the sets on the chain gears?

Because Katech builds motors properly. Using the timing chain gears is notorious for being very inaccurate, and can be off a few degrees at best.

Well, it doesn't have an adjustable cam sprocket. I wouldn't trust that anyways. Using cam logic is the professional way to do it.

Thanks Haans

Thats a fancy bit of gear, I just use a degree wheel and adjustable timing sprockets.

Stang's Bane Feb 26, 2009 09:57 AM

I understand how the Cam Logic obtains the readings for the degree portion, but how will it change how the cam is degreed in with no adjustable timing setup??

Sorry for the hijack..

Pull the pin in the cam and adjust the stock sprocket.

Why did you go a little milder on the cam?

What DCR are you are expecting?

The customer wanted the torquer cam, but he said his wife doesn't like the lopey idle.

10.8:1 DCR

I'm guessing you are using LS7 heads.

Results: 615hp / 557tq

When we get the FAST 102mm manifold I expect at LEAST 630hp.
