What is the proper stud size for a 95 LT-1?

The 7/16" or the 3/8th"?

Also the Rockers I'm interested in are Non-S/A
what else will I need?


"Crane Non-Self-Aligning Roller Rockers for use with 7/16" stud will clear 1.630" OD springs.1.6 Ratio"


"63-1302-16 Comp Cams Pro-Magnum Non-Self-Aligning Roller Rocker Arms, 3/8" stud, 1.6 Ratio"


Thanks for all your help guys!

Stock it is 3/8 but it would be good to upgrade to a 7/16 stud. Also for NSA rockers you will need guideplates.

Forgot to mention if you have a 96-97 you will have to get hardened pushrods for NSA's. I believe 93-95 came with hardened pushrods stock. Not sure on the 95's though.

How much does it cost to upgrade to the 7/16" stud ? what do I need to do exactly?

I got the 7/16th ARP studs, cost about 29.00 through summit. All you need is the studs, 8 gm guideplates, and the NSA roller rockers designed for the 7/16th stud.
