My G3 Builder did a 67 Barracuda Notch back earlier this year race weight is 3200 , stock 6.4 Truck short block ,SRT392 NON-MDS cam, Apaches that were milled .030 , Car went 7.10 @96 with the XV Intake manifold and 6.81@ 100 with a Modified Ritter., I would think the cascar intake should crack 7.0. The Cuda runs a Twin blade carb and MSD Hemi-6 Ignition . they are running 5.57s in a Dana shifting @ 6600

On the dyno it made 515HP@ 6600 with the Ritter intake, I forget what he said it made with the XV , I think it was in the 450460 in the 6400, but TQ was crap.
