Which flywheel do i use in my ls1 swap? Attempting to bolt an 01 5.3l truck motor to a 93/94 4l60E 2wd tranny with what I believe is the proper torque converter for that tranny. The tranny case does not have a removable bell housing if it makes a difference. The 5.3l flywheel bolt holes are just slightly larger than the converter holes on the 4l60E by a couple of millimeters. Anyone know what flywheel to use in this app and if I need a spacer or not? I've been through the forums but i believe I am more confused now than when i started. Man you guys have a lot of info here. Thanks!

You need the spacer and can either ream out the bolt holes on the flexplate you have or buy one with the proper spacing. I got the kit from advanced adapters for mine since I needed the flexplate, bolts and spacer. The part number is in the link in my sig. The 93 trans was a 4L60 non electronic which would have a throttle valve cable still. The 94 you won't be able to control the torque converter lock up with the 01 pcm. The 95-97 will work though.
