hey a got a 93 chevy 3500 (454) what gears would it have in the rear end im thinkin somwhere around 373 or 410 but bowhay thinks itll be in the 270 rang any help
My 93 k3500 454 dually had 4.10's. There's a decal in the glovebox with a bunch of 3-letter codes on it. One of them will tell you. I'd be happy to check Alldata at work to decipher the code for you......
ok so just write down all the numbers in the glove box and send them to you o and ya thats what i told him but hes swears on the name chevy itself that its 270 range
hope this helps.
IN YOUR GLOVE BOX THERE ARE CODES GM USE'S.
TO FIND OUT WHAT GEAR RATIO YOU HAVE HERE THEY ARE: GU4 IS 3.08 .... GU6 IS 3.42 .... GT4 IS 3.73 AND GT5 IS 4.10 THESE ARE THE GEARS THAT COME IN 81-04 FACTORY AND IF THERE IS A G80 BY THOSE CODES ITS POSI.
I hope you bet Bowhay money on that gear ratio , you would have took it , never seen a 3/4 or 1 ton truck with a 270 ratio , he must have had his thinking cap on backwards that day :lol:
just ribbing you Bowhay
