The Offy D64 was the same manifold but for the 64-65 273 heads with the odd intake bolt angle. This one is the D66 for the later 273 and 318s with small ports and modern intake bolt angle. Both really good intakes and I'm surprised this is still here. It would really be good on a pretty hot 273 or 318. Hard to find.
