69 big-block
 

recently purchased a 69 vette with a 427-390hp motor. car has been in storage for last 20 years orso and only 220miles in last 12 yrs. just finished tune-up, belts, hoses,ect, and car has plenty of powerbut smokes out left bank cylinders. not a coolant loss, but definately oil, sporadic at times,not enuf mileage yet to see if it will foul plugs, not too sure how to approach this, ideas or comments appreciated. jg
