Thanks just seen your v8 height thread. dude that engine is massive. Im really worried about the dif to be honest. its going to be a nightmare to mount. =( the skyline dif is a 4.1 ratio do you think i can get away with a 3.9 sierra one instead or maby a 7.5inch cossy one? (RB25DET - twin-cam turbo (T3 Turbo) ~245 to 250 hp and 319 N·m) ~wiki) my one will be old so not that much power. it would save sooooooooooooooo much trouble,
Also can someone measure how high the center of the dif shaft center is from the table top? just so i can get the gearbox inline.
Thanks again all
Edit found out my gearbox ratios i dont have a clue at all about this kinda stuff all those cogs are confusing. So can anyone who knows whats what, advise me to the best dif for this 'RP71C #2', the ratios are 3.32, 1.9, 1.31, 1.0 and .838.
