Good day hope this is correct thread, I am working on my 64 malibu ss and looking for diagrams/pics/general info for installing rochester 4 jet onto 1963 327/300HP, had old 4 jet on when got the motor,purchased a new figured it would show up with everything but missing a couple things i.e. dashpot. Some assumptions and a little internet surfing I think the heat tube is going to be ran from exhaust(tapped in), dist. to vacum port at front of carb and break vac to back of carb. This block has the casing vent on the back of the engine which I have installed grommet and PCV which I was going tie into the back of the intake with the transmission vent. I think I am going in the right direction but if not maybe someone could shed some light greatly appreciated thanks in advance
