Thottle body spacer
There is a shop here that makes them for LT1's and LS1's. I got kicked out of there cause I said to someone there that was looking at one to buy that they aren't worth a **** for that reason, one of the guys that works there heard me and kicked me out..lol
They offer a HUGE gain IF you get one with nitrous and fuel ports in it and use them.
To the original poster. We were all there at one point so don't get upset, but sounds like you are stuck at the early newb stage where you mistakenly believe the cheap catalogue crap and magazines are good. They are not, TB spacers, ignition upgrades, fancy sparkplugs, TPS enhancers, IAT resistors, hypercrap, tornado, all crap. Only exception would be ignition upgrades, they are largely wasted on stockish motors and even moderate NA motors but can be useful with boost or spray. The aftermarket's first priority is taking your money, once in awhile stuff actually makes power but it is not the rule.

on a big-dick-daddy setup, wouldn't a TB spacer help add plenum volume? similar to how people have cut the back of the intake off, and welded in a "dog house" to increase plenum volume?
I know 95% of us will never take advantage of something like that, but if a spacer was cheap (like free, or you made one) it wouldn't hurt anything to install it..
