andy, are you planning on also trying the intake with 2" tall adapters when dynoing ? the racer from canada believe his name is don (with the heavy charger)always used 2" risers with this intake. think he was the one that said the ch-28 would not mph but would et better than the other intakes he tried. also in the past have seen old engine pics of stock/super stock cars using the ch-28 intake and believe they also used 2" risers under the carbs. must be worth something, on the track anyway but maybe not the dyno was just wondering if the risers would show anything on the dyno. they must help at the track for all these cars to be using the risers. and on your book lots of good info.
