So i got a 92 pathfinder and a 84 datsun 720 pick truck.?

I was just wondering if i could rip my v6 out and stick it in the datsun. Would the tranny line up or would i have to use my pathfinder tranny……Both are 5 speed….
would motor mounts line up too?

Dude, here’s the deal. Motorheads have been cramming big motors into small trucks since the dawn of time. No matter what motor you put in your truck, it is not going to match up with anything under the hood. An inline 4 cylinder motor has different motor mounts and a different transmission bolt pattern than a V6. It is a different design, it is a different size, and your 720 was not designed around a V6. There were also no computers controlling the 1984 motor like there are controlling the 1992 motor. None of this means you can’t do it. Later model Nissans were equipped with V6 motors. Small-block V8 motors were routinely crammed in to Datsun pickups starting with the 520 model like I had. But it is a given that the stock transmission, even if it could have been adapted to the big motor, would have self-destructed in short order. If you are serious about putting a V6 in your 720, it is going to take a lot of fabricating of motor mounts, transmission mounts, computer and electrical system modifications, steering linkage modifications, driveshaft fabrication, and a buttload of big and little things that you can not even imagine. But one look at Hot Rod magazine or any of tons of other publications and websites will show you that not only is it possible, but if you have enough time and money, you can put almost any engine into almost any car. One big factor, though. Once you have this 1992 motor and transmission installed in your 1984 720, good luck registering it.
