rustyoldZ Posted January 11, 2017 Share Posted January 11, 2017 Does anybody know if there is any issue fitting the super magnum t56 behind an ls without modifying the trans tunnel? Thanks. Quote Link to comment Share on other sites More sharing options...
blu240z Posted January 12, 2017 Share Posted January 12, 2017 Don't know about super magnum but my t56 magnum fit had to grind down a small portion of the trans case in my 70. 240. Quote Link to comment Share on other sites More sharing options...
wayverippah Posted January 12, 2017 Share Posted January 12, 2017 I had an f-body T56 at first and had to bang out the tunnel. I switched over to a T56 magnum when I added a turbo and had to bang it out even more. Quote Link to comment Share on other sites More sharing options...
alainburon Posted January 14, 2017 Share Posted January 14, 2017 I have a T56 Magnum and did not have to modify anything on the trans tunnel. Mine is a 78 280. Quote Link to comment Share on other sites More sharing options...
TimZ Posted January 14, 2017 Share Posted January 14, 2017 (edited) I have a T56 Magnum and did not have to modify anything on the trans tunnel. Mine is a 78 280. I'm looking at mounting a T56 magnum behind my L-series in my '78 - were you able to clear the mounting ears for the stock crossmember? Measurements I've made so far look like this point will be really tight - there's only 8" between those ears. Also, where did your shifter come out? It looks like the standard magnum shifter location is too far forward and the XL is too far rearward, at least for where it would end up bolting up to an L-series...

alainburon Posted February 3, 2017 Share Posted February 3, 2017 I bolted my T56 Magnum behind an LS3, I removed the factory trans mounting ears from the trans tunnel since the aftermarket mount I purchased did not use the factory mounting. The T56 Magnum I used was modified to fit an F-Body Camaro, the shifter came out in the center of the factory hole. The stock T56 Magnum shifter point is too far forward. You can purchased the F-Body modified T56 Magnum from Tick Performance. That's where I got mine. Quote Link to comment Share on other sites More sharing options...
