Well, alright guys! You guys have me convinced. I’m going to yank the motor to degrease and replace the rear freeze plugs, then I will replace the manifold with the performer

I also made the mistake of running an Sp2p on a 318 but at least it was given to me. I honestly think the car ran better with the stock intake and carb.
