BTW, also, don't think that it can't hurt to just run it, and if it blows, it blows, no loss. For all we know, the cranks, rods, heads, etc, might all be in good condition, but things like bad valve springs, leaky exhaust, clogged fuel system, can destroy what could be a nice engine in about 5 minutes. So something that might cost 2,000 to go thru and check, might cost 5,000 or more because it greneded.

When i bought my first go fast boat, I had low oil pressure. Everyone kept telling me not to worry, since it was a new engine, and thats its just a bad gauge or sending unit. I didn't believe that. I had the engine pulled, and tore down. Turned out to be the main bearings were severly worn, and several other issues going on. If I had just "ran" it, i probably would have destroyed a 900.00 crank, a brand new Dart Big M block, and alot of other expensive pieces. So what cost me 5k, could have cost me 2-3 times that to fix/replace. Just trying to steer you in the right direction dude!
