I've never heard of graveyard motorsports. Personally if I cant find good reviews and usually some peoeple with personal experience that I can physically talk to I wont go to a shop or vendor. Many times the "price is right," type of thinking will end up costing you twice as much as getting it done correctly the first time. Your best bet will be to go on your local chapters sub forum and talk to some members there that have personal experience with the shops in the area.
Otherwise that sucks your ringland is toast. Sometimes i still feel like these engines are hit or miss when it comes to making some poor. I've seen blocks go out at stage 2 levels, but I've been running mine at 320/360 (mustang dyno) on e85 for over a year @ 24psi without an issue. I religiously change my fluids, monitor (log) the car for knock ect, and if somethings wrong I stop beating on it. Otherwise I drive the piss out of the car. I can't imagine buying and modding a car and then never even getting into boost.
