lq4 to powerglide help! Ok folks, I'm pretty new on here and need some help with mating this lq4 to the powerglide I just rebuilt (hopefully correctly). I had a guy helping me that instead figured he'd come and steal my tools some cash and some of my parts, needless to say, he isn't coming back.
I know people have asked the question before, but I can't find anything specifically discussing the lq4 to a powerglide tranny. What do I need for the flywheel to converter connection? I just picked up a 2500 stall hughes converter for the tranny (I didn't know people were putting out special converters)
Apparently I can drill the converter holes out on the flywheel correct? Besides running a 7/16" bit (if I remember right) through the holes do I need this spacer everyone keeps talking about?
Sorry to ask a redundant question, but again, I'm not finding anyone addressing a powerglide in their swaps.

#LS1-700 its about half way down the page. I just came across it in my search so I have no feedback on it yet. I'm running a lq4 with a glide too.

Do you know which year LQ4 you have? The 1999 to early 2001 LQ4's had the correct longer crankshaft flange (and flexplate) to mate to SBC style converters with not much hassle. 2001+ LQ4's had the shorter more conventional LS style flange that all other LS motors have and would need the converter hub pilot spacer and either redrilled/oblongated flexplate bolt holes or the correct LQ4 flywheel that has the right bolt spacing. You could also use the TCI flexplate.

mine is a th350 but for some odd reason i needed not adapters or anything to mate up to my lq4. everything bolted up perfect the flexplate even had an extended bore for the snout of the converter. think when i ordered the motor it was an 01

The last TH transmission/converter I installed I used the GM flywheel/spacer kit for the '01+ 6.0L, in the past I used the TCI setup but it was not available at this particular time. I snapped a few pics of it and will attach some to this post.
You can see the spacer and longer bolts, but also notice that the torque converter bolts lined up without redrilling. I'll try to find the part number of the kit.

Awesome Joseph. I did some searching and found it. Click on the more info and there is a good artical.
