When I did the swap, I didn't start out with a working motor, so I refreshed as much as I could. I put on a new water pump and thermostat. I recently swapped over to an 11 blade. The radiator is original to the truck, so it could be an issue. I replaced the whole distributer when I did the swap.

Before running the recent log, I checked the timing (est disconnected) because I thought it might be the reason for the lack of power and overheating. It was at 12 (not sure how), and I adjusted it down to 0-2. The truck runs better, but lacks power. The radiator could be a weak point, but it shouldn't cause power loss.

Any other ideas? Are logs not a good diagnostic tool? Thanks for the responses.
