	4A-C and the 4A-GE are different motors.  They share a common block, but
that is all.  The pistons, rods, etc are differnt.  The big difference is
the head.  The -GE head is DOHC, whereas the 4A-C motor is a pushrod
engine.  Looks are decieving, though, as the 3T-C motor (1.8L, 80-83
corollas) was also pushrod but has been used for 150 hp/7000 rpm reliably.
	The 4A-C is a cheap, reliable motor.  The 4A-GE is more performance minded.

>But maybe the 4V motors have larger components.
They are different in all aspects except for the block itself.
