hi! i've got a holley 390 going on the 250 in my 65 nova wagon, along with clifford intake and headers. as of now, the only other mod is a 194 head. will the stock fuel pump be enough to support this setup? any thoughts would be great. thanks
I've run several different configurations of carbs equal to or larger than 600 cfm on my 292's through the years and all of them had stock fuel pumps. You shouldn't have any issues.
