What has to come out? I heard the rad, fan, belts, grille. Anything else? How tough is it to do yourself?

 

Well I dont know if its the actually swap part thats hard.... You just have to keep the lifters up...

The hard part is having all the tools to take the other **** off..
and the knowledge of putting it back together...

 

for mine i took the fan shroud radiator water pump front cover cam gear rocker covers rocker arms spring push rods and starter and front pully its not to hard to do.

 

I didn't pull my grille. The cam swap I found was easy. The springs were a PITA though. At least till I got a good spring compressor. I'm ready to do it again

 

not necessarily hard, but time consuming. like white1 said, the springs are a pain. the damn oil pan to timing cover bolts (2) were a pain for me to get started when putting it back together.

The cam swap was easy IMO except for thosw two bolts. I have LS1 fans though. I'm thinking of putting my stock cam back in and selling mine so I can go bigger . Its not hard once those springs are done. I had a hard time getting the pully back on, but I think I figured out a trick for that.

 

If you don't mind me asking what kind of trick did you figure out for putting the pulley back on because I had one hell of a time getting mine back on. Might be doing another cam swap soon and I am dreading getting that damn pulley back on again.

 

Its probably not a good idea, if you do it, put some grease on the outside. I took a butane torch and heated up the INSIDE of the pulley, and put it on by hand except for about the last 1/4-1/2"

 

I've read just to heat the pulley up in the oven for about 10 min, "slides right on"
