LQ4 Th350 Do I still need Spacer?
Well Im getting ready to pick my Lq4 soon and Im kinda starting to want to keep the Th350. So I have been looking around and I foundthe whole spacer thing but then I checked TCI. They have a flewplate for th350 to ls based motors. I'll put up the link with the table and the link for just the ls th350.
Table is halfway down the page.

Heres the actual flywheel.

Re: LQ4 Th350 Do I still need Spacer?
you will need the spacer unless you have a converter designed to fit the th350, with the long hub for the ls1 crank.
the short hub on a std sbc converter isnt long enough to mate up with the crank on the lsx motor.
if you got the lq4 from a 2500-3500 it should already have the spacer on there.
you can use the stock flywheel from a 2500-3500 series trucks for a th350 as well.

Will I be able to change to a T56 later down the road if I want or will the spacer cause huge headahces because I had orginakly planned to use a 4l60e. THat was thrown out because of the power I'll be layin down.

The early Lq4's have a thicker flange than the lq9/ls1's. You won't need a spacer if you have that year. You will have to elongate the bolt holes on your fly wheel to bolt to the tq converter. As far as a t56... you'll have problems there cause the thicker flange.
