Pontiac59 Posted October 24, 2011 Share Posted October 24, 2011 If 55 is the same, I might be able to scare one up. Link to comment Share on other sites More sharing options...
Guest danceswithpumps Posted October 24, 2011 Share Posted October 24, 2011 thanks, but I think GMC used the Pontiac 347 only in 57.Rod Link to comment Share on other sites More sharing options...
Pontiac59 Posted October 24, 2011 Share Posted October 24, 2011 GMC used Pontiac V8s from '55-'60 or so, in 287, 317, 347, 370, and 336 variants. The manifolds and routing don't change much, both 55-57 cars and trucks the left manifold dumps at the front and wraps around to join the right on the right side of the vehicle. The truck in question is marked '55 and clearly has a Pontiac V8 in it (with GMC stickers on the valve covers). Link to comment Share on other sites More sharing options...
Guest danceswithpumps Posted October 24, 2011 Share Posted October 24, 2011 Sounds good! Thanks for the info. Let me know if you find one and what you want for it. A pic would help too.Thanks,Rod Link to comment Share on other sites More sharing options...
Pontiac59 Posted October 27, 2011 Share Posted October 27, 2011 I know it's up there on a truck, I just have to get there before they scrap it. '55 like a 2-ton conventional cab. Might be a week or so, it's 45 miles away, but I have to go anyways, I need parts for my driver and they have the best price on what I need by a long shot.
