Tony, I now have a 69 C-10 with 300 hp 350. Still has the spreadbore manifold, trying to decide on which carb and whether to go with an adapter or to put on a squarebore manifold. Probably will g with the adapter to save some time right now, I need to get it to the tag office.
Also, any suggestions tracking down an exhaust leak? Dang engine is so loud I can't track it down closer than which side. I put in an exhaust gasket set yesterday. New engine, new headers, and it had no gaskets. I tried pouring ATF through the carb, no smoke. Next I tried Kroil, got some, but not enough smoke.
