Ya, 400+ horsepower out of a rotary VE pump just doesn't cut the mustard.

Is your truck a 2 wheel drive? If so I have heard there is a problem with oil pan and steering linkage. You may be able to find a pan that won't get in the way.

If you have a 4X4, you have to cut about half of the front cross member out and box it back in. You will have to fab your own motor mounts, transmission mount, lengthen front and shorten rear drive lines.... Don't get me started.

If you can fab/weld/visualize, and look on line at others pictures and description of how they did their swap, it is not that hard, and at least for me a good diversion from the job that puts food on the table.
