On a '75 460, is the factory intake a spread-bore or a square-bore design?
Also, how much of an improvement over the factory manifold is there if I switch to an aftermarket unit, like an 'Edlebrock Performer'?

Square.. Ask me how I know.. I used a 74 460(D4LF) carb on my 76 torino 351w w/weiand intake.. I would believe the 75 was the same.. As far as the swap on the 351w the carb had a choke stove & electric choke assist but the weiand intake didn't have a provision for the choke stove.. The weiand intake also had a generic mount pattern for the throttle bracket..I only used 1 bolt to attach original bracket.. To be quit honest I believe this carb was to large for the engine as I never did get the engine to run real good..You can see the set-up if you look in the classified ads under Pics of 76 parts car. Also on page 2.. Its differant than the 76 parts car ad.. Its pics of 76 parts car |

75'S went to a spreadbore 4350 motorcraft carb, which ultimately got replaced by Holley's from an early TSB from Ford. Also some 74 460's had Thermoquads on them, I have one in my stash unfortunately is no good. The Ford fix was a kit that had a small spacer and the Holley carb to replace the 4350. 4350's had a bad problem with a plug by the filter inlet blowing out and dumping gas all over!!
