saxfiend1967 Posted March 5, 2009 Share Posted March 5, 2009 I have a 406 the front header tubes 2 and 4 are not getting hot I have adjusted valves several times ,checked compression and checked for external vacuum leaks. I have checked timing (numerous times) rejetted carb the list goes on and on I will do the propane test sat ,I think the intake is leaking from the bottom. I also get a pop throught the exhaust every so often too in addition the car seems to want more initial timing than is usual ,20 degrees,there is no vacuum advance I have 15 degrees of mechamical advance . alsop these are dart heads 200 cc runner with 750 holley double pump .I have 17 pounds of vacuum at idle and 180 pounds of compression any ideas?

saxfiend1967 Posted March 8, 2009 Author Share Posted March 8, 2009 FOUND IT!!! never trust wire looms. I had wires in a loom ,the #2 wire slid back in the loom the number 4 slid forward (when I changed heads and plugs) I didnt check them because I was sure with the looms tightened against wires this couldnt happen. lesson learned dont ever skip the small stuff even if you know its right. I took my best friend for a ride he was screaming at the top of his lungs like a little girl UNCLE UNCLE slow this sob down halfway through 3rd gear,LOL Quote Link to comment Share on other sites More sharing options...
