i have a 1986 K10. it came from the factory with a 305 and 700r. i got it with a 350 th350. now the kid i bought it from said the ring gear in the rear was shot so they put one from another truck in it. i got it running today and in 3rd gear it goes about 45 or so at what sounds to be 3000rpm. could they have put a 4:10 in the rear?
