YUP Methanol Injection is good stuff. I used the snow that had
the handheld programer/info. You can adjust when the boost juice comes
on in a "ramp up" stage. You'll need a good vacuum/boost source and
a place to install the tank, pump and the inline solenoid AND the regular
solenoid that goes before the throttle body.
I also have it on my SBC 94 chevy truck and love it. I was able on it to
change my timing retard from 1.5* per lb of boost to 0.7* of retard per lb
and noticed a big improvement at the track on it and when towing hard/heavy.
