Now that I have a few more supercoupes I suppose I can include them in here as well
black 90 5spd - rebuilt engine split the crank due to improper radius, head gaskets were fine, no tellin when the originals blew
red 90 5spd - about 39k on the rebuilt engine and they let loose on I-10 when I was beating on her, she got hot due to a coolant leak
blue 92 5spd - casualty of testing, I was paid to blow them at about ~70k, let loose on I-55 due to running lean (testing purposes), new rebuild free of charge
titanium 91 auto - blown at about 120k, driven like it was stolen its entire life
orange 93 auto - grandma blew the head gaskets at ~130k driving from south carolina here to new orleans, she wasn't watching the temp, possibly a stuck thermostat to blame
black 94 5spd - crapped the gaskets at ~110k when the potential buyer came to test drive it
92 titanium auto - crapped the gaskets at 110k for no apparent reason
my other black 90, my red/black 90 and my 95 purple auto all had the stock gaskets before i rebuilt the engines with no problems at 180k, 90k and 120k
all 10 of them now have arp heads studs and all except for my 92 auto have mls gaskets, knock on wood I have yet to blow an MLS gasket
