Hey, everybody. Got just a quick ? about holley power valves. I know you check your vacuum at idle and divide that in half to get the size for the valve- but the catch I have run across is do you check it in park or in drive? Tranny is 350th automatic. My vacuum in park is 14 in. and in drive it it 9 in. So do I get a valve of 4.5 or get a valve of 7 in? Thanks.
