Datsun Z-car
I just picked up a 1974 260Z and am trying to get my links and ducks in a row.
I have found mention of Johns cars inc. and none of the site links seem to work.
JTR site seems to still be all SBC. Though I see mention of JTR LS motor shorties here repeatedly on threads.
Any help is appreciated.
If you can't post their names or links PM me info.

JTR does not make an LS swap kit, but they make better LS shorty headers than Johns Cars does. They also sell the rear drive shaft flange you will need to convert to bigger U Joints.
For long tube headers go to hybridz.org and search around. They had a group buy some time ago and I think the thread is still active in their LS section.
Be forewarned, they are a pack of constipated ****** over on that site. Post what you just did over there and you will get a pack of lap dogs yipping at you about using the search tool and following the rules. Read through their stickies and FAQ links at the top of each section and you will probably find everything you need to know. You won't even need to open an account.
