Thread: How hard would it be to build a racing transmission myself?

Get the 7/8 th's chain. It's a lot stronger than the 15/16th's. The 15/16th's are junk and people running 12's have broken those chains. The stock chain is good for that much abuse.


I think the main problem with the 15/16th's is that it does not stretch and just breaks


Trust me. I have heard it is actually a 7/8'ths chain but the only difference is the gears are a little wider and different shaped. Gm actually used to use this chain but does not any longer becuase of the fact that it is junk.
