Ok so i got a zzp transmission last summer (before i knew about 3ep) and got 3.29 gears, 4340 input shaft, and a 2500 stall. Only things i cheaped out on was getting the chrome moly pump shaft and a single chain. Question is... is it possible to upgrade to the single chain without pulling the trans? I'm just trying to get an idea on labor because when I got the trans done my mod "to do" list was pretty light. Since then I have changed it to s1x cam/headers/fs ic (just installed).
Also, when should I be worried about the stock dual chain giving in? It's new with the rebuild with 17000 miles on it. I try not to do any 3-1 downshifts, dont run slicks, and only go to the track about once a year. Thanks for the help guys!!!
