Top Swapping, what do I need to know?

Hey guys,
I'm top swapping my 02 GP GT in 2 weeks, what all do I need to know? I've heard that on a Top Swap a 3.8" pulley is the same as a 3.6" on a GTP. What's everything important I need to consider? Tried to search the forums but didn't find much. Links to other threads would be appreciated as well.
Thanks!
 


You have everything you need for a top swap?

-Heads
-LIM
-Blower
-Tensioner
-GTP PCM

I'd suggest to do headers with the top swap. Its the perfect time to install them. Grab some Speed Daddy's off eBay for $220. You'll be on a high compression block, with stock manifolds that breathe no better than coffee straws, and a blower that makes a bunch of heat. It's asking for trouble. In that case, headers should be necessity, especially when they can be had for so cheap.

I don't know what your budget is, but if I was going to top swap, I'd do the majority of mods I wanted to do now, such as Springs/rockers/Gen V/Northstar throttle body.
