I just bought a 1963 SWB with a running 230. The motor smokes and after taking off the air cleaner I noticed that the carb is leaking. I think it is the seal on the other piece which rises above the intake manifold. I thought the carb should be a Rochester but it is a Carter YF. Both sets of numbers (neck 6-1658 and 1535) I have taken off of it have led me nowhere with respect to rebuild kits. I would like to evaluate the engine whether it is shot or not but I am afraid to run the truck long enough for the exhaust manifold to start a fire. Where should I be looking for the right number? Since the motor smokes and smells bad should I just punt and find another I6 of SBC? Any help would be appreciated. A search did not yield much.
