swapping 71 2.2 for 74 2.4 what's involved??

[whackit]

Okay,

so that's a crazy general question. but i can get basically for free a very good 2.7 core complete (incl cis). I was planning on rebuilding my 2.2 but what would be involved with swapping the 2.7? can I use my original tranny? i have a set of webers so i could maybe just put in some new pistons and replace the injection... anyone? I need to act fast.

thanks.
