Actually I am considering a small Roots (Whipple Charger) Blower.
When I used the term forced I meant it :)

Upgrading to forged pistons, And if the $$ work out Mopar Performance
Aluminum High Flow Head. Like I say, this is the research stage, 

I get about 120 Hp now and Set an arbitrary target of 140 as a design 
goal. The trick is I want to do a bypassed turbo or Super charger
with a demand clutch to shift it in and out of the system. I'm leaning
toward the mechanical blower because in my 4x4 throttle response is an 
issue. 

Mopar has a complete performance kit for the motor that bumps it to 
about 160 HP but its MAJOR $$ ,, Around 5K. And its all High rev power.
 
Heck if ya don't check out all your options how are you going to empty 
your wallet.

My checking account seems to have the ability to go from full to
emty in < .4 seconds.... :)
