Stock DZ302, Holley 4053 - While I've had numerous SBCs over the years, I've never owned a solid lifter motor / car until now. I am interested in checking the valve clearance as it seems a tad noisy to me. I read from the Chassis Service manual that the clearance should be 0.030" (intake and exhaust) while hot. I understand the manual to say that they should be adjusted with the motor idling (?). I've adjusted newly assembled hydraulic lifter motors running numerous times but am not clear how this would go with feeler gauges and the solid lifter motor running. Please advise on what the preferred method is - statically with the motor warm? Other? I don't know for a fact that the cam, etc is stock but believe it to be.
Also the car doesn't want to idle warm less than about 1200 rpm. I know the spark plugs were replaced before I purchased it. I need to verify other basics like the points, timing, etc. but am interested in other's thoughts regarding purchasing a rebuild kit for the Holley 4053 if other basic parameters check OK. The external portions of the carb look great but have no idea how old the internal parts are. The inability to lower the idle and have it maintain a normal idle is something I want to correct. Thank you!
