here read this guys, so if i understand this right a century converter has a stall of just shy of 2100 rpm?? may i dunno cheaper than buying one from zzp if it works like im thinking .....i just got off the phone with my dad about what 1 inch chain will work in the 4t65e, and he said he thinks it was a non nothstar v8 fwd trans he is gonna do some research for me... and i will post up info tonight...

The 4T60-E featured a 245mm torque converter with varying stall speed and gear ratios. Stall speed is the rpm(revolutions per minute) that the converter reaches maximum efficiency and is correlated with the engine and vehicle weight for the best combination of power and efficiency for the vehicle. (For example a '95 Beretta features a 1650rpm stall converter as opposed to '99 Century converter with a stall of 2095rpm.)
 


Having trouble following some of your post but I'll see if I can make it out. What year/make/model of car are you working on?

Buy a rebuilt torque converter with the stock stall speed. I'm a big fan of Precision.

Now onto the 1" chain. There has been several 3800 companies looking for a cheaper solution for the 1" chain option. The ones that you are talking about were never made for a production vehicle. The 1" chain was strictly for GM Racing and that's where they started. Now for the 2nd option that you have is to use a 7/8" chain which was used in the 4T60-E. To go a little further there were 2 different versions of the chain that was put into the 4T60-E. Earlier years were pin type and later years were rocker type. Both option require the gear sprockets to be machined to be run in the 4T65E
