3.4l swap?

Those of you who have swapped a 3.4l in place of the 2.8l, what did you need to buy in addition to the long block? I plan on getting one with a carb to keep it simple.

What years camaros should I be looking at?

What are the power gains from the 2.8 to the 3.4?

I will be swapping it in my 86 MJ with the A904.

I tried searching and only had mild luck since 2.8l or 3.4l are to short to register.

Here's a write-up on the swap, hope it helps.
