has anyone run this throttle body spacer on their 454??? If so what do you think of it? It's a hard swallow for 150.00 I would like some info and maybe some feedback if someone is running one thanks guys...
If the manifold is a WET style then it will make a difference.
If it is a DRY style manifold, then there will be NO difference.
Wet= injectors above the throttle body
Dry= Injectors at the bottom of the runners near head
I have one, dont waste your money. If you really want one I will sell you mine.
To clear it up a little more if your engine is throttle body (TBI) up to 1995 then it may give you a slight improvement, probably not much, and not worth the price.
If it's Vortec 1996-up then no way in hell...forget it.
