Update time.
I took the car home from the shop and got busy with other stuff around my house etc.
I ended up putting the small Eddy that was on the 440 back on my F..d 460. Guess what, it runs the same on that engine. Crisp, clean down low..........and a higher rpm miss type of a sound, just like my car.
So, I am going through my 750 this weekend. I have new gaskets and a complete unmolested parts 750 that is the same PN.
We'll see what results I get from the Holley.
Just an update. More to come.
