Does anyone have any info on these 60 degree V6 engines. I found this wiki on them. http://en.wikipedia.org/wiki/GMC_V6_engine
Do they have the Small corporate bolt pattern?
Anyone have one of these?

they are not related to the current 60v6 engines, there was a thread on this about 6 months ago.. the search might pick it up

Huge, horrible looking engine. Looked more like an IH. Gas mileage? Forget it. Must've had a 6 inch stroke. My cousin had one we used on the farm. That's all it was good for. It might have had iron pistons. It looked "industrial". Some early Ford 272 in. "Y" blocks had iron pistons, they looked just like the car engine. 40-45 mph top speed in a car. Impossible to blow up. Set a brick on the gas on one once and after about a half hour it got hot and stopped. Cooled and started back up. Alot of strange designs in the fifty's and early sixties.

Those engines aren't exactly a bolt-in. Back in the day, they were used in dump trucks, semis, and the like. Jay Leno has a V-12 version in a fire truck.
