$4400 for that engine is a very good deal. I've seen a few people post that they have spent more then that for a 3L swap.
Hmmm.
$1000 for "self" built engine
$600 pistons
$1000 rods
$500 machine/head work
$300 injectors
$1000 custom cams and oil squirters
That's $4400 already.
They even throw in a DMD & SVT flywheel.
So this means SCAT and WISECO have the designs to make rods & pistons respectively.
