The total timing is all in at 2200. Distributor has 2 of the light springs in it but I have other springs coming from Mancini to slow the curve down. Probably shoot for around all in at 3000 and go from there. Currently has a 6.5 power valve but I might try a 10.5. Its got a lean surge when the throttle blades are almost closed. Feels like “fish biting” when going down a slight grade.
