I have a 460 with a ported head, 39 fcr, stroker hot cam and I am having a prob jetting it. The fcr pilot jets are hard to come by and I cannot read the numbers to see what size is in it. It was perfect before when I was running the same setup but with a 426 piston non stroker. It had the same pilot but had a 185 main now I have a 205 main and it takes fuel but when u nail it cuts out hard. Let me know guys. Thanks
