I am in the process of installating a 1957 235 in my 1951 1/2 ton truck. I purchased a short water pump with a narrow belt pulley. Can a use the harmonic balancer from the 57 engine? It has a narrow inside belt pulley and a wide outside pulley. Will this fit without any radiator modifications? Also I guess I will need to get a narrow pulley for my 6 volt generator. Can I swap my 216 intake and exhaust manifold to the 235 motor? The 235 intake does not have a horn tab and the exhaust exits towards the rear and not straight down. Any help would be appreciated.
