The WOT afrs look ok. For this one test.
It shows you are in the ball park @ WOT. But drag testing (MPH) will show you what WOT jetting
works best. (The afr gauge is just a guide) It is just one of your tuning tools. There is no perfect WOT AFR to target. Some engines like a bit more or a bit less WOT jetting. Thats what drag strips are for.

Try the new jetting I recomended for the 600's and tell me how it does.

Whats the chances of picking up a new or good used 750 carb body to get the 750 carbs back in service.
Might be worth a call to Edelbrock. (defective replacement) You use a lot of their stuff.
Might get some product support.

The key with a tunnel ram on the street is YOU GOT TO TAKE IT OUT AND DRIVE IT.
It needs to get warmed up.... It gets a lot more street friendly once some heat gets in the manifold.

Why is the idle AFR so lean?
