340 engine timing issue

We need to know what side the lower rad hose is on first, so we can determine what side the timing marks are on.....don;t get a head of your self because you will make more problems.....did you do what i said in my first posting and what these other guys are telling you?????.....plus you have to remember you messed w/ dist, the timing is off.....I guarantee it....and sure you may have a carb issue if it wans't tuned after install....and you are looking for a vaccuum leak because...it runs rough..could be, but lets find some timing marks and get it close to where it should be...then if it still has a rough idle, procede from their....you don;t want to drive it w/ timing out of wack you will burn a piston, because it is tough to hear a spark knock when you are driving it.......tell me if I am wrong guys...but i have tuned a bunch of these small blocks from 70 and up.....keep us posted.....stay calm it will come to ya...
