So my dad bought himself a 2wd Chevy truck this weekend at an estate auction. Supposedly started life as an in-line 6/3 speed truck, now has a Chevy small block and a 4spd. Runs strong. Very strong. The son of the deceased previous owner told dad afterwards that the small block was a 327. But I’m having a hard time believing it given the 3 year production life span of the 327. It’s just a two barrel. But I’m guessing 305.
