The cammer motors are not new. all 4 are used orig motors. The new in crate blocks are the 427 side oilers. Warranty blocks. The side oiler block is slightly different then the cammer block. The cammer block has a
oil return hole being fed from the head back down to the pan. The side oiler blocks can be easily modified and have the hole drilled in the block for the
oil return. In fact I had my machine shop do this to 2 addt'l blocks. gave him 1 of the orig blocks to use to set up the milling machine. He charged me $200 each to modify the blocks. my orig cammer motors have CA5 #'s on 2 and the other 2 appear to be modified 427 side oiler warranty blocks. Sorting out and packaging into motor sets now. Only found 3 427 HR heads. I'm going to keep a set so I'll be selling 1 HR head, 1 set or MR heads and 1 set of LR heads. I'm building a collection of Ford Muscle Car motors to go along with my Mopar collection. 1 orig date coded 406 tripower motor, 1 427 C5A sideoiler with HR heads and 4 bbl manifold, 1 date coded correct 428 SCJ with 2x4 manifold and correct carbs and 1 cammer motor 4 barrel set up. Also have stack fuel injection set up for a cammer and 427 LR. Many more sets of 390 HP heads, used blocks, ford alum manifolds, lakewood bell housings, etc. I'll post all what I have to sell once all sorted out and decide what I'll be buying 1st. Also told to look at all the 289 blocks as I think we have some C4, C5 and C6 blocks. I know we have some ford 289/302 alum 4 barrel manifolds also. Also found some sets of the rare short and long tube exhaust manifolds which were used on these motor/car packages. Way to much to sort thru in our spare time.
