I believe that code on the 70 Nova 12 bolt is actually CBS, not CBR, CBS is a 3:55 posi code

Re: 12 bolt from 1970 Nova
 

I'd bet the R is actually a B - can be hard to read those codes, especially when those guys were hitting round tubes with those stamps! Sometimes they almost dent the tube, but a lot of times they are light on the bottom.

CBT is a 3.55 code...I think CBS is 3.31.

U R right, CTB is indeed a 3.55 - I shoulda caught that, I have one in my '69 Nova!

Why you!!! I aughta......

In '68 they were a Chevy II Nova https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Re: 12 bolt from 1970 Nova
 

As I recall....

CBR = 3.07 posi
CBS = 3.31 posi
CBT = 3.55 posi


I'd sure like to find one of those CBW's attached to a car.

Isn't CBW just a 3:31 open?

I know in 69 BW was 3:31 open, and I thought the 70 just added the "C".

Thanks.

Old age here. I was thinking of the BM code, which is 3:31 open. Hey, upside down it's a "W".
