I purchased a set of yella terra 1.7 rockers from a fellow ls1tech member who didn't have the shims that some with these. Would ANYONE happen to know the thickness of these shims? I've searched high and low and can't find anything. Any help would be much appreciated.

 

TTT
Anyone?

 

One more try....

 

I've got them in the parts bin and I will be able to get you the numbers you need by tomorrow morning.

 

I'm curious as well. I'm going to be using .062" shims on my Harland Sharp rockers and am wondering if that will present valve cover clearance issues or not?

 

I've had trouble locating them and my last spot would be in my attic. I'll keep looking but I would also try contacting Yella Terra for the shim size.

 

Thanks man. Anyone else?

 

Found em! .49 thousandths off my dial calipers. Sorry for the wait. Hope this helps ya out.

 

.049, or 49 thousandths.

 

Thanks a bunch guys!

 

.049 Was a little tired typing that one.

 

You can get different size shims from McMaster Carr. On my Yella Terra's I ended up with 0.090 shims to get a centered narrow wipe pattern. You really need to check the wipe pattern to determine what size shim to use. Almost every uses at least the shims they provide about 0.050.

He is pretty well versed on setting up valvetrain . . .

 

Haha... I'm hoping after 2.5 years that the fella got his yella's set up
