So I picked up this 3rd member from a guy, it was advertised as a 4.4:1 ratio. I couldn’t pass on it for the price. Looks to be in good shape. Coming to closer inspection I see that it is stamped with a 42-10 ratio, witch should be 4.2 ratio. I’m curious about these oddball ratios and not a whole lot of information on them from the searching I’ve done. I plan on trying this 3rd member out with my gasser build. BBC 454 with TH400 tranny and roughly 30-31” tires. What do you guys know about these?
