Hey 347 owners. The techs at Blueprint advised me to cap off the vacuum advance and rely totally on mechanical advance. This motor is brand new with the sniper still in learning mode. I'm using a simple bpe hei distributer with no ignition box, nothing fancy here. Please reply if you think disabling vacuum will adversely affect drivability with my hot rod. I built this car to be reliable and I am trying not to cross over into the black art of tuning and maintaining a race car motor. This car will be driven daily. Your advice is appreciated very much.

Also, anything wrong with using standard prestone antifreeze in these aluminum headed motors and radiators?

Thanks,
Tom
