I have a chance to buy a 1961 TBird parts car with the original 390. I have not looked at the car yet, but the owner says it is the original engine. According to my Steve Christ book, the 5th digit of the VIN identifies (which is "Z") the motor as being an HP engine and that it has an
oil pressure relief valve at the rear of the block. It was unclear to me if it would be a solid lifter cam motor - anyone know? All I know is the 1) Z designation and that 2) it is a 4 barrel. According to the book, same designations for a 1962 would be a 6V motor. Would appreciate any help with the particulars (solid lifter or not, were all '61 TBirds the same, estimated value, etc) - as much as possible w/o having the casting #'s (trying to save myself a trip).
