I have a rebuilt 87 stock block- still standard in my 87 gn thats coming out in two weeks to make room for my new roller/billet capped engine- the motor only has 800 break in miles on it since the last owner rebuilt it and when i bought the car and drove it home- motor ran fine but i was looking for a more durable racing engine. $2000. will deliver up to 100 miles from new york or meet someone halfway.
