bad luck or what

[grayghost]

I have 2 85 olds 442 and both have the fangs on bottom side of the housing does this mean they are 7.5 rears or what?
i know one of the cars is a true 442 by the 8th digit in the vin being a 9
only 62k miles on it the car has been sitting for 6 years.this car will be for sale.

Probably, post up a pic and we'll double check...

I know back when I was researching for an alternative rear end for my 7.5 rear end, I read the two fangs indicate that the rear is a 7.625 rear end which were typically found in monte carlos. My 7.625 rear end that I put in my malibu is from an 86 monte carlo ss and it has the two fangs.

The two fangs indicate at the very least it's not an 8.5... I've read some of the 442s didn't get 8.5s.

...I've read some of the 442s didn't get 8.5s.

All '85-'87 442's recieved 8.5" rears, as well as the '84 Hurst/Olds.
However, the '83 Hurst/Olds was built with the 7.5".

All Olds 8.5's had 3.73's, whereas the Buicks all had 3.42's.

Thanks for the correction. I remembered there was some performance-oriented Cutty that didn't have an 8.5 and thought it was the 442.

The 8.5's had blocks there instead of fangs post up a pic so we can tell what you have there.

You have a Monte with a 7.5, just compare it with the Old's. If they look the same, you have a 7.5, if not the Old's is something else.
