Move this pig ! 340 B body ....

Well , somebody had to say it I guess. I can freshen it up myself here at home if it doesn't need boring , and would be a good idea when I pull to paint engine bay, I know al this. My focus was best route to go with original 340 in this heavy car to gain decent performance - I still like the turbo thoughts. Hate to be immature about it at my age- but my buddy drives a 73 RR, 4 spd with stock 400. I wonder how the turbo'd 340 would match up to his ?
