A friend of mine has this car but is unable to tell what size engine is in it. 350 or 390. if it will help here is the vin #476B65L834868.

interesting.. why have you not done a Vin search? I put the vin no. you gave and it said not enough numbers?
You don't say which model it is. is it a 2 bbl carb or 4bbl carb
65 for sure are either an FE or could be a Windsor 289...
where did the vin number come from ?
From the outside except for a 427, FE engines all look the same
