Conversation Between Hendrens Racing Engines and Barrett_57

HI , I am new to 4m and was looking for some advise. I am trying to get into crate late model racing with a 604. I need some info on whats the best bolt on parts to use? Like carb, spacer, water pump, pulleys, headears, oil, oil filter, air filter, distributor, plugs, wires, and fuel. I have to buy it all anyway so i might as well try to get whats best.
