Anyone one know or where I can look up what rear end gears came in a:
67' GTO

Had a '67 GTO some years back equipped with the standard 335 HP 400, TH400 and factory A/C. A 2.93 rear end was standard issue with that drivetrain/option combo.

Another question for the correct Tech forum...

Assuming they haven't been changed and it is the original rear end, probably 3.08's

Jeff,
Not where I can look yet., but I know my 65 shop manual has em listed on like the first 8 pages or so.

Lists police, taxi, etc.

Pm me your number and I'll send you a shot of whatever I can find when I get home in my 1967 shop manual.

Merry Christmas Eve!

2.93 is what I've run across under '67 base 400 4bbl cars.
2.56's under AC equipped 400 2bbl '67's.

Okay thanks for the replies.
All have a Merry Christmas !

my 67 base 335/400 auto AC also had 2.93 open

My 67 convertible, A/C, Auto.4-bbl also had a 2.93 gear. It is stamped WD on the axle tube. Do you have the rear end? Here's a link that might help:

My experience in CA has been that the AC equipped '67 GTO's had a 2.93 as standard, and the non AC '67 GTO's had a 3.36. 2.56 and 3.08 were never 'standard' ratios.....they had to be ordered with the car. 2.93 with a TH400 in a '67 is a great gear ratio to drive with, these days.

Thanks again and Merry Christmas!

My unmolested 1967 w/ac had 2.93 also.

My last two, 335 hp/turbo 400, 67's had 3.36 gears.

and they were factory non AC cars, I'd bet...

only way I've run across to get more gear than 2.93's in a factory equipped Auto AC '67 GTO was to have ordered the 400 HO engine, then the GTO received 3.23's.

Yes, they were non air cars.

if the rear hasnt been changed and teh gears are still what came from factory,on the left axle tube there is 2 letters to denot what the ratio is in rear
