Yesterday afternoon, John B. from Jomar and I had this coversation. He wanted to test a 750 cfm carburetor with the appropriate tapered spacers. When we are ready to test the 750 cfm tapered spacer; if you are willing, we can use your carb for the testing. We can test at different volumetric flow rates and see the differences. Let us know.
Jay
Jay,
You just may have made me an offer I CAN NOT refuse.
Would it be OK if I sent you both the 750 and the 775 and my spacers?
I'll send you a copy of my build, and my future intentions, if that would help you determine what is best.
Thanks,

Re: Carb Spacer - Airflow Test
Jay,
Thanks for the explanation. That's the only plausible reason I could think of, for your testing at 20.2" H2O. Again, nice test and it's appreciated.
Note to the guys, we've been running Jomar Power Cones for a few years now, and sometimes the carb pad on the manifold needs to be opened up (or ported), to match the exit of the Jomar. IMO pad to manifold "matching" is required.

To put some context to this post.....Charlie's statement is mostly relavant to the powercone spacers for the big bore 1250 & 1450 dominators.

Nick, you should make this one a Sticky ! This subject about different spacers pops up from time to time.
Re: Carb Spacer - Airflow Test
so does this have similar results with nos plate engines or is this for n/a engines? Was just wondering if the plate would effect the flow

Re: Carb Spacer - Airflow Test
when you are stacking the spacers, the Jomar goes to the carb, right, lay the open spacer on the intake, am I right?

The Holley That Tried to Whip My A$$
And almost did but, I almost have her beat after an untold amount of hours and some grief. I have been messing with Hollwy's for 30 plus years and have learned a ton of new tricks in the past month since I starting semi restoring them and this one has taught me the most so far. Ton of build pictures coming soon. I will do my best to make it so everyone can see them without clicking any links but here is what I started with.

Bear with me The new Post.Img.Org is not Loading
Let me know if you can see this picture. I may also move this thread to somewhere else so as not to clutter up this section.

Not the Same Carb. Just so you can get an Idea of the Process
This was another one I rebuilt and sold. It was a nice carb. and an easy job. If you get too carried away most people can't/won't afford them for the average vehicle.

^^^^^ All Back Together
This was a List#7010 Also a rather Unique Holley aimed at Fords but had many other applications. The semi spread bores with square base flanges are no longer made and they get very good mileage combined with reasonable performance on mildy modded engines. It's already been sold and going on a Ford 351M/400 with a Holley Street Dominator intake that went with it. Waiting to hear back from the customer on Vehicle specifics and how it performed for him.

Re: Carb Spacer - Airflow Test
About 5 Holley cores came in yesterday and 2 more on the way. The 800DP was rough but is turning out to be a beauty queen. Had a fresh kit in it with blue gaskets and new power valves and for some reason someone left it in the weather. I will post before and after pictures of it when I am done. Also picked up 3-400 dollars worth of Holley Kits and parts for 50 bucks so I am well stocked for parts for not a lot or out lay. Going to be real busy until Sunday and hopefully most of them will be Ready for the Auction Block. If you need/want one better speck up before then.
