Pat is correct in saying the original "highriser" 427's were centeroilers. From 63 to early 65. Is it being advertised as original? I know the sideoiler came out in late 65 and might be possible it was at the crossover point but his is my speculation only. What is the casting number and date code from the block? What are the casting numbers on the heads and intake?Check everything out carefully on this and be sure date codes are correct and match the parts if being sold as "original". Look for the C4AE-6090-F heads as these were used until early 65. it should be easy to see all numbers being the motor is apart. G.
