1972 GMC 1500 Longbed Drivetrain Question
 

Thinking about buying a 72 gmc Longbed listed here locally on Craigslist. Engine suffix code is VO826TDD
I know It's a 72 350 engine but I want to know how much Horsepower it came with from the factory. Also 72 GMC Truck is a Manual 4 Speed on the Floor, I looked at the trans under the car but could not I.D It. Looks nothing like a Muncie or saginaw, Anyone know what the original 4 speed transmissions were in these trucks.
