Default Overdrive for th350?

hea guys i have a th350 in my car and i would like it to be more street able... i had to go back down to 323 gears and i would like to go up to 342 at least and would like to be able to cruse at least at 60 on the free way... now my question is that do they make an attachment to the th350 to give it an overdrive? i have heard off this from someone that i worked with and i would like to know what the attachment is called and how much it would cost to buy one if there is even something like this available...

It's alot less expensive to install 28" tall tires. You could run 3.73's without any problems. Your 3.42's will be perfect. I sell Gear Vendors. They work well, but have issues like expense, modifying floors, etc. 300-500.00 in tires or 2500-3000.00 in a GV + mods. It's all we had in the 70's, and it worked.

Are you opposed to a 200-4R??? Your stock driveshaft "may" work but you would need a new converter. http://www.extremeautomatics.com/tra...ons/2004r.html
