Pat, the main reason for using the 3b as opposed to an AAN - fiding an
adu/aby in US is next to impossible - is that the configuration is more
compatable with your chassis. The AAN intake manifold is all wrong as are
all of the accessory attachment points, water pipes, radiator, etc. 3b more
or less drops in, relatively speaking. The main limitation of the 3b is the
ignition and older design of some oil routing I beleive. There are some
other points, but the reasons you would want an AAN is these updates.
Coil-on-plug ignition is a big deal when running extreme boost.. However,
everything I have heard says you can get 300hp from a 3b and not worry but
you would want to consider a larger oil cooler. As for stability, your 7a
must've been a lemon cuz these motors are built like the rock at Gibralter.
Once you crack one open, just pay close attention to preparing the gasket
sufaces and proper torque.
