    I went to check out a pair of mid 80s 150hp black max engines. They both had what looked to me like the poppet valve was cut in half.( Imagine the sideways 8, the smaller circle of the 8 looks like it was cut out) Anyone have any thoughts?? Would this be a deal breaker, the guys wants 1k per...

    rebuilding V6 150 hp black max

    I have a few of these black maxs. I am planning a rebuild of one. 5 of the 6 cylinders have 120-130 psi, one cylinder has 0 psi (hence the rebuild). My plan is to have the dead cylinder bored out and have the other 5 cylinders honed. Would having the other 5 cylinders honed and replace the rings...
