My buddy is moving and we came across a factory short block that he had bought out of Flint back in the day. He's thinking about selling it - whats it worth???
wasn't being a smart as and would have been interested in buying as i'm in need of a 109 just was wanting you to post more information I asume nothing.
all replacement blocks after 88 were marked SG1-------that signified that it was a "service" part--------largest application after use in the 89 trans am was for the API oil testing program-------GM made them available for that program long after they could be purchased as service parts
