Then just try and find a th350 converter with the longer LS snout....unless you find a deal on one with the short snout then you will need this spacer.....

Some spacers just slide on the converter and now its long enough to slide in the back of your crank..........some spacers depending on the converter you might have to weld it on.....then take to Jarvis so he can true it up on his lathe......takes about 5 minutes and about $20.........my Circle D th400 LS converter has a snout that unscrews so you can screw a longer snout on......vary slick.

Also if your LS motor had a t56 behind it you will need to pull the bearing out of the back of the crank....i got lucky and a slide hammer worked..
 
Not sure what trans it had behind it originally. I would love to have a Circle D piece but cant justify the cost at this time, maybe later down the road. Thanks for the advice Sir.
