square/round tooth cambelt question

[stevei]

came across a big problem on my 1600 nova engine when i was checking it for a oil leak:



it has the incorrect crank pulley fitted, a round tooth with a square tooth belt and vernier. The waterpump is a round tooth item aswell. Rather than the costly option of a new vernier i was wondering if any other small block 8 valve engine has the square tooth setup? i have been to the scrap yard today and found 3 8 valve engines around a '91-'94 model year to have the round setup

The only square tooth pulley i found was on a tigra 16 valve engine. The pulley i removed tuned out to be broken ( woodruff casting ripped off )

This pulley has 23 teeth where as the round one has 19 teeth.

Just need to know what engines and model 8 vauxhalls had the square setup? from there i can figure out what cars to look at.

i'm loosing the will, this is prity much all thats needed to finish my car now aswell

please advise me guys

cheers

Im sure my old 1.2 is round tooth.

[stevei]

now thinking the best idea is a new vernier as then i'm leaving the other pullies as vaux intended

Are all small block verniers the same? they all seem to have 38 teeth, is it just a matter of matching up square or round tooth?

Yes, its the tooth shape that differ.

AW06-The 1200 carb block i had, had square tooth setup.
All my later 8V's have had the round tooth setup.

If the crank sprocket and waterpump is roundtooth, id just get a round tooth vernier to match, and cambelt.

mine was a 89 carb 1.2 with round... I dunno.
