when did they switch from a 208 to a 241 x-fer and why,? whats different? were there differnet 700r4s as far as output size.I found an 84 shortbed near me and the thing has no motor or trans in it , the guy said that the tranny core he had to go with it was worth something because it was a heavier duty one with bigger output. I am familiar with 2WD stuff and know the differences in certain year 700's as far as upgrades go but I never heard of different out put sizes. thanx for any help ,DAVE Always searching for that pot of gold!Got any old musclecar parts lying around????
