Just a thought here,
Installing the TBS with the K&N intake forces the intake tube to hit the fan blades (after shroud is trimmed)....so....If I relocated the fan a couple inches towards the radiator by using a longer rod coming from the pulley would this solve my problem, or just create more problems?

I dont know if this is feasible, but any input would be appreciated. thanks

 

Actually, I remember reading on Jeg's about a kit you had to buy for H2 hummers and one other vehicle I think, that relocates the fan a tiny bit forward to allow room for the throttle body spacer. You could look into that! It was super cheap, like $10-$15 I think.

 

I did notice a little increase in fuel economy, but as southbay said, I can't keep my foot out of it. Also performance increase was nice.

 

those 88-98 trucks youll notice a larger gain than on these newer 5.3s do. i noticed a very nice big gain on my 5.7 after doing this.
