Holley 6619-1
Is anyone familiar with a Holley 6619-1? I can't find a Ford application, only Chevrolet. I know it is a 600CFM, just don't know how well it might work on a FE 360. Any ideas?

Bear, the carb doesn't care. The guy at the parts store does as he's having problems finding the right kit and float, and I'd like to know if anyone is familiar with it and how well it works on an FE.
It was just a question.

God, please take us back to the 60's when there were no computers and the parts guy actually knew something about cars and engines.
The carb is a Holley 4150, 600 CFM with vacuum secondaries. Of course it will work fine on your 360. You might have to rejet and put a step or two stiffer spring in the secondary vacuum diaphragm, but otherwise any Holley 600 CFM vacuum secondary carb will work fine.

I had 2 separate parts men at 2 different shops looking for a kit. We looked in a total of 5 different books and only found 6619 listed in the application part of 1 book. The carb says "built by Holley for Motorcraft", yet the only application we found was on GM products.
When I looked this # up on the internet it said it was a 4160, not a 4150, so that's the kit I bought. Is there a significant difference in the two?
I just want to get this right this time. My old carb is just shot.
I have also heard I need a spacer under the carb?

Did either of these genius' look in the Holley book. I would figure that that Holley would build a kit for it since they do list it as one of theirs. If it says "built for Motorcraft" then had to have been used on a Ford. Holley says the Renew kit is 37-720 and the Trick kit is 37-933. And I haven't worked in a auto parts store since 1970 and that was only part time.
Oh and my proof reading is bad tonight. The carb is a 4160, the model without the full sized rear metering block.

The 6619 was a 4160 type 600 cfm that was "calibrated" for a 350 Chevrolet, pretty popular amongst the "Car Craft Crowd" in the late 70's and '80's, had some upgrades and a higher price tag than a plain-Jane 1850.
One thing you never want to do with a Holley, is use a parts-store off-brand kit in them- get the real thing, the gaskets, needles, etc. in the jippo kits will give you headaches. The cheap Holley Renew Kit for 4160, about $25, should fix it up, has the gaskets, needles, etc.- a speed shop-type counter guy should have them on the wall behind the counter, and Summit has them

You can use it or don't, it's up to you. If the spacer was oem on the vehicle you should use it. There are 2 main reasons for the spacers;
1. To keep heat soak to a minimum.
2. To accomodate the manifold design and/or throttle linkage.
If you are in an area where high temps are the norm you might want to use a carburetor heat shield also, commonly available from Jegs od Summit.
