It will suck after a while. I have 295/50's on my v-8 blazer daily driver, which is a tad over 27 inches tall, and 3:73's. With the t350, I was a tad over 3000 rpm in drive @ 55 on the interstate, and everyone was passing me like I was tied to a post. I ditched the t350 for a built 700r4, and cruise 70'ish @ 2200 rpm...
