Anyone have some first hand experience on any performance improvement with a spacer on a B4B??? With or without Q-jet?? thanx
I ran my B4B with a 1" spacer and it helps a bit. I used it in conjuction with a holley 950 HP and the fit is tight, but it will work with a drop base aircleaner. For me it helped the mid and upper part of the powerband. Good luck. John
