You have some COOL Toys, Ken! I miss my FJ, sold it a while back because we were getting too old to get beat up driving that beast (350, 750cfm, headers, trans splitter, lockers, yadi yadi, yada). Got all my parts from Specter Off-Road in Chatsworth, CA. Here's a link if you don't already have it (mostly pre-85 Landcruisers).

When I did the 350 conversion, there was absolutely NOTHING legal about the engine/emissions, so I sold it to a kid in Oregon. It's crazy what kind of prices they get for these FJ's nowadays.
I bought my Range Rover new in '91 (Classic - Great Divide Edition). Much more comfortable and still very formidable. Still rocking it with 297,000 miles.
If you haven't already known about the website Expedition Portal, here's a link. It's a very cool site for serious off-roaders. Free membership, navigate to the forum, then navigate to the Toyota/FJ/Landcruiser page (the website is for all makes & models of 4x4s). You'll spend hours on it.

Peace - Out!
