What is the axle code for a 3:31 posi for LS-6 Chevelle?

Posi 3.31:1 is CRV

and CRU for non posi. Codes are all the same between the LS5/LS6.

Hi Rick:
I was not aware ls-5 and ls6 used the same code. But now it makes sense why someone cloning a ls-6 wanted my spare ls-5 rearend so bad. I donot sell and kept telling him it would not be the right code. LOL Oh boy. Still learning after all these years. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

All the 454 Chevelles in 70 used a special rear end (heavy duty ring and pinion), a unique pinion flange and driveshaft. That is why it is so easy to clone an LS-6 if you had an LS-5 to start with. The engine and tach are really the only thing different between the two.

And Fuel return line, some times.

Stefano,
If I understand you correctly you are stating that sometimes they are different betweent the LS5/LS6? They might be between the 454 and a 396 car but not an LS5/LS6. This was purely a date/plant thing. Mid year production went from a single line 727 pump to a dual line 768 pump regardless if it was an LS5 or LS6. As an example, Annie's 1st week of January LS-5 has the dual line and 768 pump just as an LS-6 would.

You are confusing me, which is not difficult to do. LS5 always dual lines? LS6 Sometimes Dual lines, based on production date/plant? 396 non L78 always Dual lines?

Then we are very much alike. https://www.yenko.net/ubbthreads/imag...mlins/haha.gif

No, all 454's started out with the single line, 727 pump and mid year changed over to the dual line, 768 pump regardless of horsepower rating. I don't study the 396 cars so I can't comment on them. Someone correct me if I am wrong however as I don't profess to know everything about these cars and could be mistaken. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Interestingly enough, I also have a 2nd week of Jan. Leeds sheet that shows a single line 727 pump so they seems to be bouncing back and forth.

Sorry guys, going on memory again and stuck my foot in my mouth. LS-5s used the dual lines and early LS-6's used the single, late used the dual. Sorry for the confusion. I need to keep my stuff handy instead of going on memory and learn to keep my mouth shut. Thanks Stefano for the ass kicking.
