As we spoke, it's not an IDEAL combo w/that much duration, old style ported iron production heads,10.3 comp. and that carb so I'll get a stock looking DP dialed in w/adj. everything w/extra bleeds so you can tune all circuits if needed.............As far as timing, I like locked w/that much duration or super fast adv. but prefer locked and also am curious as to how much cranking comp. it has because it DOES matter and I now for the first time in years run a PCV valve w/a homemade oil seperator and I love it and only a few miles due to rain but intake/plugs are clean..........
