347 stroker kit?

If it's going to be a farm truck and you just want more real usable power, I would opt for a 351 Windsor swap. The engine would bolt to your existing transmission and mounts and many other parts as it's basically just a taller block than what you have. While the HP on a stock engine isn't that great they produce more torque than the 302 at a lower rpm due to the longer stroke and better rod angles. That can further be enhanced if you put a roller cam kit into it and a lighter intake with one of the bolt on EFI kits. Buy a used engine and build it as you have the funds and time. You won't fly down the road but if you are actually using it as a farm rig, hauling wagons, moving feed and cows, towing a trailer it will far outperform the 302 or a stroker kit.
