i bought a 75 grabber to build a drag car out of. it had the "hi-po" 122hp 302 2v with a c4 3spd auto with the 3:00.1 rear gears in the 8inch housing. from the factory it was the fastest maverick you could get period. course when i was done with it it had a stroked 351w with a art car c4 with 4:11's. wish i never got rid of it. oh and you could get a grabber all the way through 77. cause i'm still trying to get our neighbor to sell her 77 grabber , its mint!
