I have two cars one is my 68 HCS and the other a 68 Ranchero bolth with I6's. Now most of the Mustangs I've seen with either the 170 or the 200 motors have 1100 1v carbs I think their Carters. On my HCS I have Holley 1v I think it's a 1940 model or 1941. I've also noticed the manifold intake openings differ the 1100 has an 1 1/2 opening and the holley 1 3/4. The parts store shows Mustangs comming with either. My question is why the differance in heads and carbs and the +'s and -'s to the two.
