1970MonteCarloNH Posted March 11, 2017 Share Posted March 11, 2017 Hey guy - is there a big difference going with a 12 bolt over a 10 bolt ? Right now I can get a great deal on a like new 10 bolt with 355 posi. I'm not going to race or drag the car just a street car Sunday driver. Should I get the 10 bolt or what for 12 bolt ?

dbreese Posted March 11, 2017 Share Posted March 11, 2017 10 bolt with the 3.55's would fit the bill. Years ago I had the factory 8.2 10 bolt upgraded the to 3.73 gears and a Eaton P-trak. I added Moser axles(c-clip style) and a heavy duty rear cover. I drag raced the car often on Hoosier Quick Time Pros and M/T drag radial and had the car in the mid 12's. Never an issue. Sold the rear and purchased a Moser 12 bolt with bolt in axles when I installed a new mill some 8 years ago. David Quote Link to comment Share on other sites More sharing options...
