If you’ve indeed checked your number on the engine and you’re sure you have a 216, good on ya. However, I just assumed (no checking) I had a 216 in my one ton and turns out it was a low pressure 235. The Big Bolts up in Canada tended to use GMC engines, whereas 1 tons and down used Chevy power. I love my 1 ton GMC with its newly rebuilt 261. Howie makes a good point. Also, check in Chev big bolts from 57-62 for the 261. That’s where I got mine. CHeck out the tech tip in the links. Welcome to the Bolt. You officially have the worm! 😎
