The answer depends on what you mean by major modifications and how much more power you want.
The 292 is probably the most major of the GM sixes with the related 230 and 250 being a little less trouble but not much.
A Chevy 261 is almost a drop in swap. A GMC 270 or 302 will provide more power and is only a little more work.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
