Top ends 6-7k min for twins and probably more like 8-9k. It really depends what you replace.

Full rebuilds, about double the cost of top ends

Mine tirnew in to a total **** storm. Not just motors turned in to drives being gone through to. Props mried all kinds of stuff. I had a real bad twisted prop shaft on the drive for the same motor with the bad lifter.

You say rockers are the killers...in all my research I haven't seen many rocker failures on blue motors in general. I saw one post from Eddie but that was from a bad batch of gold crane needle bearings.

We just did ours. I'd budget 5k a motor. In the end ours was close to that but because we found things after it was opened which is always the case. Our rebuild:

-8205 plus springs
-Manley valves
-rl931 lifters (morel 4603)
-gaskets
-mil head
-t stat housing W/ cover
-push rods
-didn't replace rockers (300 hours on them)

Runs great. 62.6 on her best day. Can usually touch 60 during the summer. Will run 58 all day with a crew. I mostly don't push it and cruise 3200rpm at 36mph
