I have a 440 ex running a wiseco 12.5:1 piston 1mm oversize valves wb1498 cam carillo one piece rod with welded crank fmf powerbomb header and white bros silencer 41mm fcr carb. The engine builder reccommended 110 octane race fuel. I was wondering what you are having luck with and where in southern ohio can I get it. Thanks

 

I have a 416 with 12.5:1 piston,Web track cam,FTZ portwork with 1mm over intakes,Sparks X6 exhaust,40mm Edelbrock carb and we run Citgo 114 in it.Wepurchase ours at a local oval race track,so if you have any near you that might be a good place to look.The last I bought was $4.00 a gallon,but I hear it took a jump to $4.75 which still isn't too bad compared to regular.
