Hey guys,
I have a question for all you who know your stuff with rear ends.
I just bought a 70 chally, and have only had a couple of weeks with it. So far everything looks pretty good with the car, the motor runs strong and everything is working alright... The engine is a 440 magnum with a 750 carb, and almost 7k worth of head work. It's a very powerful motor... whoever had it before me set it up like drag car. I have already replaced the carb with another 750 with larger primaries and a choke just so it would idle better and start no probelm. I have not really gotten to drive it on the road yet, but will soon.
When i first put it up on the lift I noticed something a bit discouraging... The rear end is a 8.75 but seems to be a "741" according to the casting. It also doesn't have a cover on the front side of the housing revealing the gears. I know that this rear is the weakest of the 8.75, which is the problem.
My question is, will this rear end hold up with such a powerful set up? I dont know exactly if the've tweaked it at all, but im pretty sure it doesn't have the sure grip, which is a no no in my book.
Any advice?
