It depends on the casting date and casting numbers. NCRS would welcome an engine like that in a car if the casting dates are before (six months) and the casting numbers are correct for the car. If it is an early '69 casting number, it won't work in a '67 L88, but would probably be fine in a '69 L88. If it is cast in late '69, it may be too late for most L88's, even a 1969 L88. This would impact the value. NCRS would judge the pad broach, assembly stamp, VIN stamp, casting date, and casting number. If all but the assembly stamp and VIN stamp are wrong, the car could still achieve a Top Flight easily. Bloomington, on the other hand, would not allow anything higher than a Silver. If the dates and numbers will work for a true '67, '68, or '69 L88, its value should be at least that as long as the correct components are there.
