Hey guys i have a 91 z28 just took out all the TPI set up and swapping to carb. New heads and new cam are going into the build. So my problem is i have bought a cloyes double roller timing chain set but i am seeing that when im trying to install it, the cam sproket hits the plate for the cam. Do i have the wrong timing chain? Does the plate for the cam really have to be there? What do you all recommend thanks!

 

Did you buy a timing set for a OEM roller cam engine?
Part # ?
The cam gear is different to that used for a non roller camshaft



It stops the cam walking out the front of your engine

 

I believe its a cloyes c-3023x. Can you give me a part number on a double roller timing chain for my motor?

 

For a roller cam use cloyes Timing set p/n 9-1145

"Will not fit factory roller cam applications".

You have to read the fine print when buying because even though a set may be listed for '87+ ,that time frame also included production non roller versions like crate and truck engines

 

So is that cam plate really needed? Whats the difference of it having and not having it? And why doesnt the older blocks have it? Im just curious lol

 

A roller cam will walk without it, roller cams didnt begin to come in production engines sbc until 87. If you want to you can use a cam button to set up end play with a non roller block timing chain set but why !

 

Oh i see. Yeah i was just curious but u answered my question thanks
