I have a '72 flatbed C30 w/ an overhauled 402BB & 4sp trans.
I get about 7mpg. It's all original including the rear end. I want to put a 283 or even a 6cyl in to improve the milage. The guys I talk to tell me it will be way underpowered and I won't improve the milage. But I see C30's for sale that have 6's in them from the factory. Who's correct? Do any of you have C30's w/ 6's in them? How are they pulling loads?
