hey guys i have an 81 k5 jimmy Im gonna start to restore. I used to use this truck as a mud toy but thought she needs some love its gonna be a road only k5 im leaving my 6 inch lift in it with 35. The jimmy has a worn out 350 with a turbo 350 tranny. Now i cant decide on if I should go with a 5.3L chevy and trans out of a smack up this would be a cool swap and you can pick these up fairly cheap. I Have been doing alot of research on these swaps also. second rebuild the 350 and maybe a 700r4. and finally 3rd some sort of diesel, cummings or detroit 2 smoker. Also what would be the best rearend ratio to go with for these 35 ? im thinking 3.73 If i go with an overdrive tranny. Thanks Marc
