Ported Edelbrock Victor flow numbers

Something else on this head was a little head scratching. I wish I would have put a check mark at the lift it happen but around .400 lift my digital Readout that is very touchy and shows me issues starting to happen started to flutter 5-7cfm much like the airspeed is to fast at the short turn. I stopped right there and checked the speed and it was fine. At the next lift measurement it calmed down and the cfm made a nice jump. (I’m thinking valve job) Also at higher lifts my thin airspeed checking tool was very jumpy at the top of the port entrance.( like an old time devining rod) Joe had made a very nice radius entry plate out of a nice thick plastic cutting board. I always use Duct Seal to radius the top and bottom entry of the plate to prevent a sharp edge so I turned off my flowbench to reshape it. It didn’t help and again the airspeed was fine. If they were mine curiously would make me dig into both those minor issues. Like I said earlier Joe did some very nice work on these heads and he now would love to have a flowbench. Lol. I’m almost 65 and he’s a touch older than I am so we are both pretty lucky to still have some steam in the boiler. I don’t see issues at all hitting his 9.40 ET target and 3550 pounds is not a lite weight.
