Gday all, greetings from Australia . So heres my problem i hope some one out there can give us a hand. I have a 1971 307 SBC, now a m8 of mine took the engine out and has lost the water pump, alternator and bracket (looong story) . How the bloody hell do you know what one to put back on. Is it the small or big one? The engine has not been bored out so its still stock if thats any help. The radiator is a PWR Custom Aluminium one. Has anyone installed an edelbrock electric pump yet, if so how do they go? Thanks all in advance
