When I dynoed my motor, we tried different carbs/manifolds and spacers.
The best numbers we got with a 4150 on a Victor were with a 1" 4 hole spacer on top of a open 1" spacer.
Since that was my best, I picked up a 2" HVH super sucker thinking it is "equal" to the 2 stacked spacers.
Anyone done any back to back testing of the HVH or other tapered spacer vs. non-tapered?
