We recently acquired a 1973 Datsun 240z as our next R&D platform. It spent it's former life performing road race duties in SCCA Improved Touring, so the mods have been limited to suspension and a full cage.
It's patiently awating brake upgrades, triple weber side-drafts and, of course: conversion to Megajolt crank fired ignition. We will have a special de-commissioning ceremony for the old points-based distributor. :)
