Usually its the ???....... Bolts coming loose on a properly balanced engine ,and I'd have no reason to doubt Wilkes is'nt, usually results from a cracked crankshaft.,or a torque converter problem..............The LS1 has a rather long flywheel bolt ,due to the fact that most flywheel setups for adapting to a conventional converter/metric 200 trans,use a spacer between the crank flange and the flexplate, so it could be more suceptable to vibration loosening it. ..... ....I've never had to use anything other than medium strength Loctite to retain the bolts on an LS1..............Engine vibrations can cause strange things to happen to seemingly unrelated components. ......I recently had to remove a harmonic damper on a BBC that had welded itself to the crank snout due to a vibration caused by an out of balance torque converter!. ..........Tom

I have a Metric 200 behind an LS1, I had the convertor made for the application. A spacer between the crank and flywheel doesn't sound appealing, do many do it that way?

ATI does. ....No problems so far on either of Matyas' LS1 cars. .........Tom

Does ATI offer a convertor that will bolt right up?, or is the spacer deal all they will do?

[Tom Goldman]

only using the ATI flywheel,not their converter. ..ATI to my knowledge ,does not do metric trans or converters. ......The adapter is only about 3/8 -1/2" thick as I remember ,it It's been a couple of months since I worked on it. ...It just provides the converter piliot . .....Tom

10-4, thanks

I have a couple of ATI converters for a TH200. They just won't build a TH200 transmission. I also have one of their LSX flexplates with spacer. Nice parts.
