LQ4 to 700r4

I know Ive read it in the past, but my old computer crashed and all my saved links are gone.

I have a 1999 LQ4 - the one with the long crank, and Im going with the 700r4/np241C for my swap. Im trying to recall what I need/need to do to make it work.

I remember that the alum head lq4s (short crank) needed a spacer and a certain flywheel, etc etc.... but the long crank wasnt as desirable.

I dont want to go the route of a custom torque converter, and im positive there was a solution to mating these together.

and yours is the long crank lq4? I know the 4l60e and 700r4 are essentially the same aside from the electronics.

Same here, 6.0 to 700R4.

If the engine came in front of a 4L80E, it has the dished flexplate and all you need to do is egg out the converter holes with a die grinder. If it came in front of a 4L60E you need the spacer with an older flat flexplate.

Either way the bellhousing inspection cover won't fit however. No big deal.

Pretty sure they all need the $40 bushing from jegs for centering the converter. Other than that I just opened up the flex plate bolts and bolted the 350 converter right on.
