Bob West Nov 6th, 03, 6:40 PM Instead of drilling the intake,you can add a 1/2" spacer under the carb. Drill and tap the spacer instead of the intake. gatewayracer Nov 6th, 03, 6:50 PM If you're carb is a non-HP 4150, it should have both "ported" and "manifold" vacuum ports coming out of the base. Hook the Power brakes up to the full manifold port. Hook the vacuum advance and transmission modulator up to the ported vacuum. If you have a 4150HP or in some cases I have seen the ports on a regular 4150 plugged, you can go with a one inch spacer with a vacuum port. http://home.swbell.net/kenladd/throttleplate.gif Robert G Nov 6th, 03, 7:27 PM I HAVE AN CLASSIC DP HOLLEY I HOPE THIS WILL WORK THANKS GUYS!!!!!!
