I believe I've finally found the new 235/244 engines timing sweet spot. After mucho trial and error I've settled on 8 degress BTDC and a hot idle of 600 rpm. Since the engine isn't stock the factory spec's no longer applied. I like as smooth an idle as possible and anything below 600 produces the lumpy idle a 264 3/4 race cam provides for those that like such vibrations. Me, I'll take the performance but I likes smooth, LOL.
