built 700R4 or typical th350

i would like to stick with a 700r4 set up and i know my stock unit wont hold up under the 400 plus tq i plan on throwing to it, and i have looked at some trans sites that build these trans but most all want crazy prices, really close to 2k or better, but yet you can get a th350 built to handle 500hp/500tq for 1k, i would really like to keep o/d but i dont want to spend 2k on a transmission, it's not worth that much to me, it wont be a drag car but i would like to run it at the strip from time to time, and if i wanted to take it on the highway i would want to be able to run 60-65 with no problems, can anyone tell me what the rpms would be at 60-65 with a 700r4 and a th350 with these set ups
tires=P275-60R15 (i belive these are about 28" tall)
gears=3.73 or 4.10

man that stinks, i want the driveability of the 700R4 but the strength and cheapness of the th350, it looks like my question on 3.73 vs 4.10's have been answered, 4.10's in a 3spd are no good for the highway, dont want to run 3k for any lenght of time, either way i guess ill be put-put'in around 55 on the highway, i understand know why i see so many fast cars going 10mph slower than everyone else

Are those your only options for gearing? With that tq you could do 3.42 and drop a little more.

I've got similar #'s with 3.42 and I run about 3200 at 120km/h (75mph) on the freeway with the 3spd. It's loud and very inefficient fuel wise, but I put in a louder stereo and remind myself the fun is worth the fuel $$, lol

it wont be a daily driver, maybe 2-3k miles a year, and i really dont want to sacrifice the strip times, i really didn't want to go to 3.73's, i really wanted to go with 4.10's or even 4.33's for better acceleration, but there is a "moving car show" (as i call it) (call cruizin) about 25 miles from my house twice a year, that i really want to get the car to, every year my wife, i and my two daughters go there its awsome, right now i own a really nice 02' gmc 2500HD with no lift but oversize tires and, and i always wash, wax and polish it up to go down there, so i deffenatly want to be able to drive my camaro there as well, and no i would rather not trailer it
