Hi everybody I'm new here, I have a 71 C-10 with a 250. I'd like it to be all it can be street wise. Going slowly in stages. Intake, carb then exhaust. Maybe a rv type cam. I'm running a Saganaw three sp. 4/10 gears rear end. I'm not building a Hot Rod but a shop truck 6 with some grunt. I'm also interested in lump port heads. Well hello again, hope to make some friends here.
