How would i go by puttin' a LT1 in a 69' Nova? What all do i need? I got the Computer, Trans, And Wiring... What else do i need?

Its pretty easy, compared to an LS1 anyway..
There's an article from car craft, I think it was the "real street" camaro. It's relatively common in the first gen fbodies, and the nova is the same so it all works out identical. I might have some bookmarks,,
