The Chevy small block and Jeep were made for each other. And
http://www.advanceadapters.com/ and http://www.novak-adapt.com/ have all
the adapters, from the transmission, shafts, linkage, mounts, headers,
radiator, for a complete job without the use of oxy-acetylene. Usually
we start this swap because we already have the Jeep, and in the proceed
spend at least twenty thousand doing it. I suggest buying someone's
divorce liquidation judgment, as this is what the job usually leads too.
Usually ten cents on the dollar.

Hey, Bill, thank you for the info. I've gotten some figures together,
including what the cost of the AX15 tranny would cost from a wreckin'
yard, the adapters, and some other information. I've got a call in to
my friend to let him know what I've found out. The most notable
information, I think, is that you can buy these things already done
pretty cheap (I love your allusion to the end of marriages which is
probably more fact than fiction; I'll be sure to pass that on since my
buddy's married with two kids <grin>).

Thank you again.

Have him buy the engine and transmission together, then adapt that
to a clocked Dana 300:
http://www.4x4wire.com/jeep/tech/engine/therapy350/ Or the Muncie M420
used by chevy pickups since the forties:
http://www.jeeptech.com/convtrans/sm420yj/ As the small block will
explode the little Japanese AX15.
