@beef stew, Thanks sharing your thougths about it. i'll go with the original setup then. but shall i raise compression to 7,5-8:1 or stick with the 6,5:1? i also wonder if you charge your 94 or 97 from the top, if the valves are closed, where does the pressure go? or even when there open, and everything is full, where does the pressure go? nice cars! should a flattyv8 run well on lpg? maybe its easier to turbocharge a six because the exhaustflow is better, and the crank gets more even load because the angle of the pistons/rods?
