Yup, it's crossed my mind a few times now (along with a 5VZ swap 
)
Do guys that run the 4.3 also run dual ultimate cases?? It would be nice to have the HP on the street but the low range off-road. What manual tranny do they run?? Will a W56 live behind a 4.3 or would an R150/R151 be a better idea?
i dont see why you couldnt run dual ultimates behind a 4.3 and i would run a R151F over the W56A/B and even over the R150F too, being as it has the lowest first gear of them all and it will help you take off on the street with them big ass tires. my opinion
