Looks like fun Alitle8 - good luck with the mod.
Are you going to do any porting?
I mentioned above, my cuz has a 98 with a vortec SQ blower on it.
He's pushing 8# of boost, all stock motor with long tubes. and wants more power.
So I did some research for him.
He decided to do the whole PI swap, but here's what I found about the intake swap.
1a- PI intake swap without adaptor kit - gains 18 rwhp NA. (naturally asperated)
To do this, you will need the following parts:
XW7Z-9439-AA intake gskt $6.08 ea
F8AZ-10153-EA alt brkt $10.53
XR3Z-18B402-AA coolant tube $19.67
F1VY-8255-A thermstat housing o-ring $3.83
F1VY-8507-A water pump o-ring $2.43
XR3Z-9L437-BA upper plenum o-ring $3.05
F75Z-8555-AA coolant tube nipple $5.73
1b- PI intake swap with adaptor kit - couldnt find dyno results but I'm sure it's a little more power because there's no
step inside the runner where it meets the head - resistance.
Livernois has a kit for just an intake, or their swap kit with the adaptors, and all the parts.
Heres a good link on the process:

Good luck.
