i'm getting stuff ready to install my engine/trany/xcase in my 71. the tranny is a 700r, there are two options that i am considering (1) move the engine forward or (2) move the Xcase back and relengthen the drive lines. I am leaning more towards moving the engine forward, any drawbacks from doing this. I have a few questions before i do this; 1) will my fan hit the radiator?? 1.1) will my belts hit the fan shroud?? 2) will the diff hit the oil pan(see note)?? 3_ will the blazer tend to "fall" forward while going downhill?? 4) will i loose some traction on the rear wheels, cause i'll be shifting some wait forward??? 4.1) will it fish tail(see previous)?? 5) will my frame weaken cause i bore 8 extra holes in it?? NOTE: i'll be puting in a 2" lift. thanks, ARQ.
