Hi,
I have a recently built 360LA No more then 500 miles on it. It is making a tapping noise and has the following symptems.

Has true duel exhaust and smokes out of the drivers side pipe only.
Will die at stops unless I put into neutral or give it extra gas to keep the RPM,s up.
Runs Decent at about 2000 to 2500 RPMS in second gear. Just running really rough.
Any help would be great -RedLeg
