700r4 or th350???

[Michael12]

So I know that there has been a lot of debate on 700r4 vs. th-350/400... Now I have come to the cross road of which one should I put in with my situation. I have a 70' c-10 chevy longbed. I am having a 383 stroker built and have 3.08 gears right now. I am rebuilding the rear-end so the options with different gears is there. I plan on doing some towing, not often other than in the summer taking the popup camper in the mountains.

If I could get pros and cons of the 700r4... how is the highway speed at 65-80? rpm? Gas mileage? ect?

Thanks,
-Michael
