Bought this past week. '74 K10 longbed with a 350/TH350 and a NP203 transfer case. Paid $1800 for it. Only a couple bubbles in the right side cab corner and a quarter sized hole in the right inner fender well. Has 2 new gas tanks, fresh rebuilt engine, new dual exhaust, complete interior. Factory cab lights that still all work. Only concern that I have is that it has a cam in it meant for a 383. Should I see about swapping it for a stock cam or will I be alright with leaving it in there? It runs fine but I don't know if such a heavy cam will effect the engine in any negative way.
