The 12V92 was 2 X 6V92 blocks with a one piece cast block girdle (upper pan) under the blocks to stiffen them. The 12V71 was the only one with a unique one piece block, thus allowing them to use 6 - 71 heads instead of the added complexity of using four 3-71 heads, it also was also only slightly longer than a 6 -71 letting it drop into truck frames. 12V71 was a fill in engine in the horse power wars before the 8V92T came along and made it redundant. I don't think the factory ever made a 12V71 out of V6 engines, it makes no sense, they did however make a 16V71 using to 8V71 blocks. Much later in the early 90's they made a 24V71 from two 12V engines, that was a sight to see!
