It has got the 360 v-8 with the auto trans and i think it is the 241 t-case. Will have to check for you on that. It towed pretty good. I towed around a 76 chevy k5 blazer on 39.5" tsl's. I towed it back to my house from the up of michigan and got around 10.5 mpg towing. I get around 14.5 mpg empty so it doesn't do that bad on gas. I just put a flowmaster muffler on it also. Give me your email and i can get you a pic of it tonight once i get home from work. If you have any other questions let me know.
Thanks,
Ben
