Th e86 is running after 3 years...but!!
 

Well got the 331 running today after having the car 2.5 years and working on it for the last year Anyway have a few bugs to work out. For one it semms to be running rich, a pesky exhuast leak at the collector,and little vibration at crusing speeds. Could a clutch for a an 89(50oz balance) on the motor cause a vibration, since it is a 28oz balance??? Just trying to get some idea's to look at before messing with it again tomorrow(3-30).. Any suggestions on any of the problems will be appreciated...

An exhaust leak before the O2 sensors can cause the engine to run rich. I would get the correct flywheel asap. Was the engine balanced with the 50 oz set-up?

I bought a billet steel flywheel for 28oz balance.. I had a flywheel for a 50oz and was about to install it until I found out the motor was balanced at 28...
