Aaron, (good name, BTW)
I don't see why not, I believe the CD2 was used on the 3.8, 4.2 and 5.3 V-12 E-Types and should be ok to swap. But if I were you, I'd send your 175 CD to a rebuild specialist and have them throroughly go through it. Funny thing how there's an internal diaphragm inside that carb that gets eaten away by what else? Gasoline!
