Can you move the sender to the other side of the manifold? If not, you could put it in the head where the stock senders were. I like them in the manifold better though.

Looks like there is a cast in boss just to the left of the thermostat housing. I'll have to check the Edelbrock manifold I have in the shop, but you may be able to drill and tap that boss for a sender.

I'm not that up on Holley carbs, so I'll leave the PCV questions to those that are. I would try hard to retain the PCV though.

I'll get back to you later.
