engine swap

g,day guys i am new to the site and wanted to ask a question. I just bought a 1978 Mazda b1800 Ute and i was wondering what engines can be bolted straight in. the 1.8 ltr petrol, 4 speed coloum shift is in it at the moment.

You're gonna be hard pressed to fine someone who could answer that question.
I wish I could help ya'.

colum shift manual? sounds pretty sweet
