In the middle of doing a TH350 swap I decided to change all the seals on the motor, and alas, I discovered my timing chain was loose as hell, so time to replace. I have a 1993 LT1 though - what options do I have for timing chains (avoiding 95+ conversions)?

The only options you have having the non-vented opti setup is to go with a stock replacement. Lunati sells one for around the same price as GM sells theirs. However the Lunati piece is a stock setup with their name on it. That's the one I'm using. There are literately no other options if you keep the non-vented setup. Below is the Lunati link for summit. Part number is lun-93094
