I think, but not sure, the Pontiac was 4 barrel carbed and the GMC 2 barrel. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | when ya can't believe your eyes, believe the manual  Bill | | | | | Joined: Oct 2002 Posts: 4,066 Bolter | | Bolter Joined: Oct 2002 Posts: 4,066 | guess so, probably built in Canada

I thought they were made in Pontiac, MI. I do not know the answer - I am just asking. | | | | | Joined: Oct 2002 Posts: 4,066 Bolter | | Bolter Joined: Oct 2002 Posts: 4,066 | just thinking.. they made the maple leaf and it was copy cat of

Buick engines went to GMC when Buick went to 8 cyl.
'50's GMC used Olds and Pontiac V-8's.

I believe I read if it was going to Canada, then a Chevy v8 was used - but in the U.S., a Pontiac. In 1955, it was the 288 (even though Pontiac called it a 287). In 1956, it was the 317 (Pontiac was a 316). In 1957 it was the 336 - I think a destroked Pontiac 347. I'll have to check that fact. | | |
