On this site, this is a religious question. The carb guys will never accept FI and visa versa.
I've had great luck putting FI on old carb'd vehicles. I've done it 3 times.
I did a Megasquirt set up on my 250 and it's been great. I got it tuned very easily. I never got my weber to be 100% right. I had issues with the float bowl due to the adapter plates for our 250. The float bowls should be at the front of the carb, not on the side. I would get starvation on my front jet during accell.
Here's a thread I put together on my FI swap. This may help you with some thoughts.
