I bought a 67 camaro which is surpose to be a 396 400 turbo car made in la accordenly to the trim tag says its a 4n car.Now I know how easy it is for someone to change tags on anything so im wandering how would I fined out what the car truely is.It has the tack and the gauge package but again easy to install and if its truely what it says it is would it be worth that much more if i put the correct year 396 with the correct year 400 turbo back in it or is just a waste of money sence it wouldnt be matching numbers?

Tom post a picture of your trim tag,, and you will get your answer if its a real tag or not

If the partial VIN on the block matches your VIN, it is an original Big Block SS. Also, post your Cowl Tag here too. The guys on this site can spot a phony in a heartbeat.
