[updated:LAST EDITED ON 30-May-02 AT 00:47 AM (EST)]this is funny but i'll say it anyway...
my almost stock '94 thunderbird ran 15.3's maybe you should just swap an engine ... by the time you put a supercharger etc + add up all your mods.. you could have just dropped in a 5.4... or went and bought a lightning .. lol!
and yes i know your truck weighs more but the tbird had 2.73 gears or 2.78 whatever the one before 96 had(96 was 3.08's)
oh and it weighed in at 4100 lb

all the above is only my worthless opinion and comments.. no flames please.
you could always drop in one of them caddy engines.. they got alum. block and the bare block weights like 98 lbs... whole engine with cast sleeves and EVerything is still under 500 if i remember right.. maybe it was under 600.....
