Newbie With 66 Special More Door!

Just signed up, have a 1966 Buick Special Deluxe with a 225 V6 that my son's gave me for Father's Day to tinker with!
Been getting some windshield and read glass issues (ie leaks) taken care of. Working on windshield area now as the back is done!
The odd fire V6 is a mystery to me as far as tuning. LOL
