Skip........ on the 2.0L Fords I built, there was about a 20HP difference between the 500 Holley & the dual 50DCO side-draft Webers. The Webers obviously being the most HP. -Dave-
Skip....... Don't remember the name @ this moment. They grind Ford cams but do NOT grind any cams for Ford 4-cylinders. All 6 & 8 cylinder only cams. -Dave-
