mas28O Posted October 17, 2002 Share Posted October 17, 2002 I know it is tight fit, but I need to here from the people that have put the lt1/4l60e into 240z cars. I am about to buy the engine and trans. I know that 700r4 fit in 280z with out to many problems, I had one. Mike Quote Link to comment Share on other sites More sharing options...
jeromio Posted October 17, 2002 Share Posted October 17, 2002 Here's how you do it. Get the old Datsun stuff outta the car. Put it up on jacks. Go get a BFH. Go drink a beer. Maybe 5. Lay down under the tranny tunnel. Close your eyes. Take a deep breath. Think of all the bad things that have ever happened to you. All the mean things people have ever said about you. All the times you broke a bolt head off or cracked a manifold or lost a job or got kicked in the nuts or got dumped by a girl. Absorb it all. Now, realize that all of that, all the pain and hardship - it was all that tranny tunnel's fault!! Go at it! Beat the %$&^#!*# out of that thing! But that's not even really enough. You'll need three or ten such sessions. It can be therapeutic. Quote Link to comment Share on other sites More sharing options...
mas28O Posted October 17, 2002 Author Share Posted October 17, 2002 When I built my 280z with a 700r4 I had to find a big hammer. Are the 240z alot smaller than the 280z cars. I have a 240z only because I live in Ca now. I just like the auto for drag racing at the track. I think that a auto trany would be alot faster of the line than a t56 z.

jeromio Posted October 17, 2002 Share Posted October 17, 2002 I've never dealt with the 280 tunnel, but I did try and put a 4L60e in my 240. I gave up and spent some dollars on a t56 instead. That auto is crazy fat, and the servo is in a bad spot, in a very sticky outy way. And then once you do make enough room for it, good luck with the exhaust routing....

utvolman99 Posted October 17, 2002 Share Posted October 17, 2002 I am pretty sure that the 240 260 and 280 all have the same trans tunnel. As a matter of fact I think they are completely the same dimensionally. Quote Link to comment Share on other sites More sharing options...
Lone Star 1 Posted October 17, 2002 Share Posted October 17, 2002 I have a 240Z with an LS1 and 4L60E. Didn't seem all that hard to me, but this was my first conversion and have nothing to compair it with. Just took a 5LB stubby sledge and moved the metal to clear the trany. Took about and hour. Worked slow and deliberate, test fitting ever now and then. I had the trany on a tranny dolly, so I could move it in and out. At no time was beer was involved in this process, but then again I not drink. Quote Link to comment Share on other sites More sharing options...
zgeezer Posted October 18, 2002 Share Posted October 18, 2002 I did a 700R4 into my early 71 Z. I carefully measured and marked where the servo touched the tunnel. With a drill and sawzall drilled and cut a veerrrry large X. Using a small rather delicate ball peen hammer I moved about six inches of the tunnel side out and then re-welded. This took about4 hours to do, counting set up. I'm doing it again for my 4l60E and I'll follow jeromio's advise. I like the zen approach and it's a lot cheaper than group therapy. By the way, there are substantial differences between early the 240Z and the 280Z. I think there must have been additional smog and maybe a catalyst in the Z. You still have to bang, but not as much on a 280. gw Quote Link to comment Share on other sites More sharing options...
