Running Hot

this may or may not help you but my 340 always ran hot (with a new build) i took the cover off and checked the chain it had so much slack in it that when i moved the dist. in either way it was still off..and you want know it because when you st the timing you will bring it up to 2000 and the slack will not be there. so if i was you i would remove the dist. cap put a shocket on the crank bolt and turn the motor and look at the dist very good. then stop turn it the other way and see if it moves when you move it..if not thats your problem...hope this helps cause i was going in from 1 thing to the next money here money there.hope this helps you out.....i replaced 2 or 3 sets of head gaskets before i found the problem:read2:


oh yea when i was running the car before i found the problem it would run 190/200/210 sometime,now 180 and i did put a alum. radi. in but after i found the problem....
