Mine has the 700R4 in it, and I have to say, I'm spoiled. I do hope to get another squarebody with a stick in it, but I'm going to turn it into a tractor: 292 I6 with a SM465/205. Very reminiscent of a Toyota LC actually, especially since their original I6 was derived from the Chevy I6.
That 700r4/4l60 and the nv1500 ought to have the same length and bellhousing pattern. Should bolt right up as long as it has the same spline count on the output shaft.
