Thanks guys...have the timing set at 11° now and is where it idles best and throttle response is better but once its driven for a while temp climbs to about 240-250 with the timing correct could this be a plug issue i was told to get autolite plugs and gap them to .054 right now has ngk g power hot plugs pre gapped but i never checked the pre gap like a fool ....also did a new furl filter last night after i try different plugs i think i might be headed towards injecters for some reason i think its running to lean ignition really only thing left is distributor coil but unsure if that will create these symtoms
