Re: [Amc-list] 290 or 304 with 4.0L pistons (Russ)

[Greg Taylor <amundaza@xxxxxxxxx>]

Hey Russ,
  FYI, Speed Pro makes hypereutectic pistons for the 4.0L.  As for the 304 bottom end mods, that totally depends on the intended use of the motor.  You might have to have the assembly rebalanced with th larger pistons.  If you're going performance with the 4.0L piston swap, you could run the forged 360 rods on the 304 crank.

  Greg; thanks for the info. I have collected three
early 242s to do my 258 stroker engine and have
several slugs left over. I'll pick out the better of
all the pistons and mess around with the core 304
engine. Any advise on what to look for or do to the
bottom end.
My 360 to 401s I usually cross drilled and chamfered
the oil passages, did an internal balance and used
quality parts. I did this on a 401 I built for a
Jeeper and he ran it to 7000 in races out at Sand Lake
all the time......Russ
