'80 ROW 3.0 in '86 Targa questions

[no1uno]

What would be involved in replacing a 3.2 with a 3.0 ROW engine in an '86 targa? Pretty straightforward or a major pita?

I have a well used '86 roller that'll never be worth big dollars without investing big dollars and a separate 3.0 ROW engine. So, I came up with the idea to have a running driving car by combining the two.

I'm trying to raise funds to purchase another car in 6-9 months. What would be best? parting car and selling engine or combining and selling as one running, driving car.

Thanks in advance
