They offer a base cal and a plug 'n' play harness for 6.4Ls, too. I have 2 running but not 100% tuned yet (spring here, will hit a dyno soon). a-e-a.com .
F&B offers a bolt-on throttle body that flows more air and is cable operated, I designed it.
No major problems into A-body, shorten the steering col jacket a bit, milodon pan, TTi headers and mounts, remote filter.
