According to the link above the Staghound blocks were cast in the Saginaw foundry. The two 270 blocks I have were cast in the Pontiac, Michigan plant. Did GMC have a foundry in Canada? My 235 and 261 Chevys are Canadian. This car is visiting from Perth, Australia. I had to go back to the track again today just to see it run again. He did quite well, I'm sure he was 3rd in one race. He was racing against flathead and Cadillac powered cars, Coopers and all sorts of other stuff from the 30's, 40's and 50's. "Old Yalla" was also racing, out here specifically for this meet. The engine looked like any other GMC to me. It had a 270H head which wouldn't be original so I assume everything else except the block (and crank???) will interchange with a regular 270. My camera broke so I had to use my phone, I haven't checked the pics yet.
