jakeoster Posted November 6, 2013 Share Posted November 6, 2013 Hey fellas, I have a 240z with a TH400 transmission and it needs some power to motive it. I'm considering building an LQ4 and stroking it to 408ci. How would I go about mating this engine to the th400 gearbox? Thanks in advance!

The TH400 is a staple of the American Transmission Category. You bolt them together! You will need a spacer for the crank unless its an iron-headed 6.0L (rare), as they have a longer snout. SO: crank spacer (simple search) flex plate, stall, bolts, drive it. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted November 6, 2013 Share Posted November 6, 2013 Yep, I did the same thing with a 4L80E, adaptor/spacer, flexplate and converter, you will be good to go! Quote Link to comment Share on other sites More sharing options...
The Infidel Posted November 7, 2013 Share Posted November 7, 2013 also might have to open up the holes on the flex plate, I had to anyways. Quote Link to comment Share on other sites More sharing options...
