Crank spacer
4l80 with a flat flywheel . Other people are trying with out it but with a converter spacer . One guy destroyed his trans . Any body have reliable info ?
I had to use an adapter to run a th400 with my LS.. but that’s because the th400 converter needed it.
Supposedly used a dished flywheel with a little converter ring . Said no spacer needed with converter . Trans broke apart on dyno . Seems there is converters out there made for a dished( 4l60) flywheel ?
