GM # 12480002. This kit does not come with studs or poly locks, if you find poly locks that fit my 3/8th studs and GMPP rr's let me know, I would like some too.


(edit) first link no go.

Actually, the Hotcam kit does come with poly locks. The P/N for them by themselves is 12367347 (qty of 16 required). The studs however are not part of the kit. Studs should be readily available from GM or elsewhere though. Tell me what you are trying to do and I'll try to be more specific. (BTW - I may know where there is a set of these poly locks for WAY cheap ;)).

In regards to the second post (hi there local boy! :)), the stud size that the rockers included with the Hotcam kit are designed to work with is 3/8" and the poly locks are nothing special - just standard 3/8" design.

Hope this helps!
-Jeff

The Hot Camkit does not include the screw in studs. The # for the 3/8 roller rocker poly nut is #12367347 for one. Screw in stud kit is #12371058 for 16.

Not sure what your doing but you do know you have 10mm upper studs and rockers and you can't mix them with the 3/8 stud to make the stock LT4 rockers adjustable. You need new rockers #12370839 (includes the poly nut). If you knew that sorry :D :cheers:

Look out !!!
THREAD HIJACKER HERE !!!

Hey, I have the LT4 roller rockers and want to use them on my L98 heads (113s)
I had a set of polylocks that look like they will work.

They fit the 3/6 studs however.
What is the THREAD size on the 10 mm studs?

Can I use polylocks to make the LT4 rockers adjustable on the L98 heads??

I can work with the valve train geometry/push rod length/spring height to get it right.
Is this worth all the trouble it sounds like it's going to be??????

Well I'm alittle worried that the factory tq'ed down rockers are not giving me the full performace that my Hotcam can produce by maybe not having enough vaccum but I'm not sure. This spring when I have my LT's and TB on I really want to make sure that the cam is working to its fullest.
Any ideas?
