Woo!! first post! =]
I am trying to find out what I would need to change out if I was to convert my 200 cid Mustang to a 289 cid. I do plan on changing out the old suspension, considering the 289 is a heavier engine. The main question I have about this is the differential. Would i need to buy a whole new rear end? or would i just have to beef up the original one somehow?
thanks a lot guys!!

Cheapest way is to sell your car and buy a v8 one to start with.Give this a read Six Cylinder Upgrade V8 - Mustang & Fords Magazine and yes you have to change the rear end you have a 7.5 now which won't take the power and there is aftermarket for them i know of.You need a 8 inch rear end at least.

Welcome!

Generally speaking, as stated here, it would be cheaper to just find a V8 car to start with.

If you can do the work yourself and have access to the parts it wouldn't be a bad idea.

Define your goals and how much money and time you have and go from there.

Good Luck!

You might also consider beefing up the sixxer. Mustang Monthly just had a good article on options for doing just that.

As stated above the cheapest thing to do would be to sell the L6 and start with a V8 car. But why sell the 6 . Take a look over at fordsix.com. There are a lot of things that can be done to the six performance wise that a lot of people don't consider just because its a L6.
