the car has a LQ9 6.0 out of an escalade, and down here in "MIAMI" we call this body of caprice a "BOX" so thats why they call it "BOXCALADE"... :? anyways the motor is COMPLETELY stock except for the edelbrock cam part # 2216, and of course the performer rpm intake 750 holley & and only a 150 shot of nitrous(to get 4000lbs out the hole!) the transmission is a 700r4, a 2500 stall converter and a 4:56 posi rear and a dirty motor! THATS IT! check out some my races on youtube"BOXCALADE" let me noe wat u think...
