1991 Z28 convert w/350?
Hi, I am from switzerland and got just recently my 1991 Z28 convertible TPI.I have a question. Where there some special order possible back in 91 to europe? Why? because in my "title" there is a 350/5733 registered and on one cylinder head there is a "57" stamp. If I identitify the VIN, it says it's an 305 TPI (F-code). The car has only 30k Miles, and everything is original, as that car came from first hand.
Thanky ou for your inputs! regards Rolf

Look behind the drivers side cylinder head for the block casting number. The rpo should be a lb9.
the computer chip in the ecm identifys the tune 305 or 350 off its letters called a broadcast code.

Auto or manual? If it's a manual it's a 305. Auto could be either but if the VIN says 305 then that's most likely correct. The title people in Switzerland are probably to blame for the engine size discrepancy.
