    stock compression on 951?

    what is the stock compression on a 951 engine? i know before i blew mine without the ada head it was 150 even but it has been bored over one size. im looking at an engine and the guy said the compression is 135psi with 90 hours on the engine, new top end done 40 hours before. engine looks clean on the outside not so sure about inside, includes stator, starter, oil pump, raves, flywheel, everything except the carbs. How much would you give for this engine? the bids at 620 right now. i need some answers quick please. auction ends tonight thanks

    Compression is 6 to 1 and my 98 951 has 135 psi on each cylinder.
