I also did not know they came from the factory with a V8 but have learned a lot about them already. 67 was the first year for the V8. It's a factory 283 three speed heavy half ton or G20. The G10 came with a straight 6. Later in 69 they offered the 307. the 63 - 66 only had a I6. They even offered an automatic trans in 69/70! but all the others were 3 speed manual. A 4 speed shifter would be a challenge
