The bungs on the headers, is that for AFR on each cylinder for tuning, thats cheating, but very smart, can you read all six at one time on a single screen while tuning, sorry I took attention away from your build with my concerns on the oil slinger, that is a very neat well set up intake and carbs, I for one like your choice of cam and combo, I bet you get between 225 and 250 horses out of that with still maintaining a good bottom end. I personally like the 264/ 110 and it would be the largest I would use in an often driven vehicle N/A, I can also appreciate the dollars you have in it. Just curios, whats your CR if I missed it.
