Default Re: 429 TJ Engine Swap question

I start out saying im pretty bad when it comes to ford big blocks. I did a little research and in 71' the mustangs cobra jet motor was the 429, so the same block as the one you have out of the t-bird. So as far as the motor is concerned I believe it should just be a simple replacement.
I really cant tell you much about the transmissions. If your mustang was originally a BB car I dont believe it should of had a c4 in it. I believe it should of came with an FMX transmission.
