Been considering installing the Crane 1.8 rockers but am concerned about the longevity of the stock timing chain with the heavier springs required for the 1.8 rockers. Has anyone put a LOT of miles on the stock timing chain with heavier springs?

How many miles are on the car?

Irrelative to one another.
I run single chains on all my cams even with XE-R lobe camshafts.

Car has 15K miles.

Predator Z, when you say you run a single chain, are you running the LS1 stock chain or some other like the LS2?

I run J-wiss but that is because I got it before LS2 was available. If I do it now I will get LS2.
