What v/8 motor will bolt up to my 1966 Ford pickup with a three speed manual transmission?

I have a 1966 Ford F-100 pickup with a six cylinder motor and a three speed manual transmission. What v/8 motor will bolt up to my existing bell housing so I can still use my three speed transmission? I've been told that a 5.0 liter 302 c.i. Ford motor will bolt right up. Any other suggestions?|||that is correct, 289, 302 and 351w will bolt up..or the big six 300..
