mialge wise im in the mid 180's... unless you take the meats into account which would tack on probably a few thousand more. as to your point frank, i am using a little bit of oil... very little. the consumption is less than a quart every 3k miles or more. not liking what your saying about the rebuild... even if racers theory is correct. the heads are new, but everything in the block is original. ive got the spare block in the shed... mabey i should start saving my pennies for the guts. just hope its not now.
p.s. i thought the bottom end was supposed to be bulletproof.
