I have two Holley 4160 600 cfm carbrueators on a 427 with a Comp Cams solid lifters and 252° and .598 lift. I bought and installed new power valves 25-8.5g It loads up missfires and will not run when it gets warmed up. The warmer the worse it runs. I figure the pluge are fouled now .I probably missed the combination completely. What jets would you reccamend also what vacum level powervalve ? I'M REALY GETTING TIRED OF ALL THE SMALL STUFF.hAD TO BE TOWED HOME ON A STRAP.I've been reading about the BG Road Demons.Bg has a new valve that fits down in the center under the air cleaner stud that is adjustable and takes careof the problems of a lumpy cam( the one often fixed with drilling the throttle plates)If I could get a couple that would work with a dual four set up.Is it asking to have car that is ready to go and not layedup all the time waiting for the next new part or adjustment?
