Searching for information on what would make the best interchange for these two blocks. Prefer to keep the Blue 72 and sell a bare black 86 block and heads. Would like to get adjustable rockers. Wonder if cams can swap/interchange over. Will be mated with a 72 904, 8.75 or ¾ 3.23 489 Thanks in advance.
