so the LSx Datsun rocks..
Couple buddies of mine (and myself) are interested in doing a 5.3 LM4 swap into this '72 240z. We're looking towards parts from Johns Cars Inc but are wanting a live axle instead of the IRS. Almost every conversion I've seen has either used the R200 from the newer Z's or the Ford 8.8 irs. But after hours of search, I can't find any hard detail on a live swap. Anybody know much about these?
They have a pretty good frequently asked questions section that should get you started.
