[Newaygo Kid]

Is anyone using a 4 barrel holley on a late model flattie if you are how is it working and did you change the jets and power valve.

Works great, right out of the box

Worked great on my prior unblown 276 and now on my blown 276. Right out of the box.

Mine works great on my 8BA right out of the box also. Has 51 jets and a manual choke.

These usually are set up rich, check your A/F

Ron,
I would like to be able to check A/F on our projects. Do you have any recommendation for a portable meter? Can any of these be used by placing in the exhaust tube? Showing my ignorance here.

Thanks for your help.

A friend of mine has this set up on a '52 pick-up he's building. What do you use for carb linkage? It's on the opposite side of normal hook-up.

Most mount the carb backwards so that it will line up with the original linkage.

Tuning one carb vs multiple 70 year old carbs is a no brainer. Mine runs great.

I also used a 1 in carb spacer to clear the rad. hoses.

You could also kill two birds with one stone by using a Ford water heated spacer. It also has a port for a PCV system if you choose to use one. Here's a set up on a Lincoln V12 which is similar to a flathead V8.
