Tony_SS Posted November 10, 2007 Share Posted November 10, 2007 What's in your 70 SS? Or what typically came from the factory in a 70 SS? Thanks! Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted November 10, 2007 Share Posted November 10, 2007 2.56:1 was the norm for a '70 3.31 for a '71 others could be ordered Quote Link to comment Share on other sites More sharing options...
Phil Posted November 10, 2007 Share Posted November 10, 2007 G80 - 12 bolt positraction rear – 2.56 was the standard ratio for the 70 SS and the 3.31 was the standard ratio for the 71. I think you could order differently though. Here is an SS link from this site. http://www.firstgenmc.com/tech/ss454.shtml Quote Link to comment Share on other sites More sharing options...

Tony_SS Posted November 10, 2007 Author Share Posted November 10, 2007 Thanks guys, I found the tech page just after I posted this. Sorry about that! Quote Link to comment Share on other sites More sharing options...
72 LS5 Posted November 12, 2007 Share Posted November 12, 2007 71 is the 3:31 gear......... bur you could order about any gear. I agree with the 2.56 for '70 and 3.31 for '71, but I haven't ever heard of or seen proof of any other gear in an SS454. Can anybody verify this with a build sheet?

Capri's 71 SS Posted November 12, 2007 Share Posted November 12, 2007 My build sheet is also the G80 3:31 for my 71 SS454. Quote Link to comment Share on other sites More sharing options...

monte70car Posted November 13, 2007 Share Posted November 13, 2007 my 70 has 2.73 in it Quote Link to comment Share on other sites More sharing options...
RARE MC Posted November 15, 2007 Share Posted November 15, 2007 My 70SS had 2.56, but I changed it to 3.31 using a correct stamped rear end from a 70 396SS El Camino. Quote Link to comment Share on other sites More sharing options...
