Pounced on a set of,,,,,328 Cam drive gears. ;)

Dang. I've been looking for exactly those to send to Scott, he needs some measurements.

Congrats to you

 

Edwardo, sorry man the 328 uses a larger concentric ring on the cam then the 308 and early QV's. in other words the large hole in the center of the pulleys there is to big for the 308. the 328's is about 1mm larger in dia so those would flop about and not center.

I would like to get some dims off them though, PM me.

 

I have hole envy. Look at all those cam timing holes - FIVE! My car only has three and I was ready to head to the drill press and make some more when timing my cams.
So the "2" in 328 is an indication of how many holes in the cam timing sprocket it has more than the original 308. I never knew that.
Incidentallly the "0" in 308 is an indication of how many cam timing holes will ever line up exactly where you want them.

 

My QV has 5 as well.

 

the early composite ones have 3 and the later steel ones have 5. and my new ones have 20* worth and 5 holes.

 

I have a series 1 GT4, so I expected to have the composite version, but I sure couldn't find anything that wasn't magnetic and it all seemed like steel to me. I've never handled any sprockets except my own, so I'm not sure really what to look for. What part was composite on the composite versions?

 

the sprocket or teeth are a molded composite, looks like they were molded directly onto the steel core. the later ones are like the above. an easy spot is to look at the face, you'll notice registers or dimples for the mold in them on the outer ring.

 

Oh, about $180.00

 

How do you if the whole idiot box needs replacement? is it missing?
