wiseguy50,

i think i would change the rearend. You're going to be putting a lot of hp to the rear and the stock rearend on these cars is pretty small. They were only built to handle around 100hp. Also, gear ratios in these old rearends is pretty tall so i think it would be easy to snap something.

Johnny Mopar is right on target. You need to change your rear end and go to one that is stronger, you also need to give some thought to gear ratio, To help determine this you need to consider what transmission you will be using, what size tires and wheels that you will be running and what the car is going to be used for. You need to get those 60 year old springs off of that car also and put some good springs on it as your old springs are more than likely fatigued and weakened through time. Give us some more info and we can give you a better answer.
