10.5 power valve ???

I had to run a 9.5 in a tunnel ram (single 4 barrel) to get it to respond properly. just keep an open mind and keep swapping out the power vales until you find the one that works the best. I have about 8/10 power valves that I keep handy because you never know which one will work best. I've also had to order special ones that aren't carried by the local parts store. If you have time to wait you can order them through ebay and save money. Once you find the correct PV you'll notice a big difference!!!:steering:.
