You could but the fuel mileage would take a beating.
You must change your stock torque converter to a stall converter with at least a 2500 to 2900 stall speed. Yes the torque converter is the big round thing that bolts to the fly wheel and it 's inside the transmission.
watch the rpms when you break stand the car
You can empty it out and change the fluid if there is nothing wrong with it and the stock stall speed will still work with the engine you will be putting in front of it. It's basically a fluid coupling. Since it's full of fluid and the fluid does most of the work, there is very, VERY little wear inside a converter. The only exception is if you have a lockup torque converter. The clutches inside lockup converters DO wear out and ultimately fail.
that all depends on what engine you have and the cam in your engine and your rearend gear and what you want to do with the car, once you figure that out you will have a better idea what stahl converter you need, other than that I would just put the stock converter in it.
stock stahl converter is around 1,800 RPM.
if you have an automatic transmission depending on what gear you put in it from stock if you don't have like a 2800 or a 3500 stall in your torque converter once you get off of the line it will fall flat on its face i would get a 3500 stall torque converter call a tranny shop and they will help you out if you have a manual transmission then you probablly got a vaccum line of some kind unplugged check all the simple stuff first its the simple stuff that will get you trust me.
I would worry more about the tranny than the U-joints, a lot of people run a stall converter and don't have a problem but it puts a lot more stress on the tranny.
For what part? Installation Torque? (Engine torque production is about 420 lb-ft )stock.

The torque rating for your stock 1968 Camaro 327 cubic inch engine is 235 pounds at 3000 RPMs. The torque rating at 3500 RPMs is 255 pounds.

Have you checked your timing? The stock torque converter could have a very low stall speed (1500 rpm) causing the power to goto the wheels well before the engine has a chance to wind up, the gearing in the rear end could also be very tall like 2:73 which is great for highway milage but poor for off the line performance, somthing like a 3:55 would give you a better kick in the pants but you will lose gas milage. A tranny shop could replace your torque converter with a higher stall one so that the engine will be closer to its power band before taking off, be careful not to get one with too high of a stall speed (like 4000rpm) because it will be a pain to drive around town (truck will rev up high and take off abruptly, not good when parralell parking). This is all assuming your engine and transmission are in good working order.
