2.8 to 3.4 swap comanche

I just recently purchased a 86 comanche. I hear many bad reviews about the 2.8 motor and ive been told that a 3.4 swaps in nicely. please give me some info about this! thanks

You can get them out of 93-95 F-bodies or crate from the GM Performance Parts catalog. The dimensions of the block are identical to the 2.8L, you just move all your accessories over. I did this swap years ago in my 85 S-10. If you're dealing with fuel injection, you need to find out more about that first but I believe you can still make things works.
