Would the 4.7 liter from my 1999 Jeep Grand Cherokee fit in an A body?

Our Jeep's transmission is toast and I'm not going to fix it... again.
It's a 1999 with a 4.7L motor in great shape.

Could I put this into an A Body? I saw a totally cool '67 Valiant for sale locally with a slant 6. I feel like it would be pretty zippy in that light car.

Thanks!

(hope this is the right forum)
