289 intake set up

[albert]

JUST went out and started my 1977 bronco,it has not been started in a near month,as it's snowing and has been all day and it's slick around here,thought I might need it,,,,pumped it a couple of times ,hit the starter and she busted right off,held it at a just above idle for a few sec's and came back in the shop to let warm up and defrost,,,,,it has a bone stock high miles 302,years ago,I put a 289 ci intake with a 390cfm,holly4bbl,electric choke ,that I made un-op when I put it on,,this carb was taken right out of the box and bolted on,,never no problems and gets great mileage....sometimes these big cfm carbs ain't the way to go ,in my book..we also found out on these high rev;ing,2.3 4cyl in these race cars,that a 3.50 cfm holly is better then a worked 500 holly....so bigger,,ain't always better,,,,been there..done that !! POP

Pops, I couldn't agree with you more, the smaller cfm carbs work better! The local car club that I am in have a lot of guys who do some serious drag racing at Englishtown (about 10 miles from where I live) and they all talk about how they have successfully used smaller cfm carbs on their drag cars over the years.

The zinc version of the "570cfm" Holley Street Avenger is actually a ~465cfm carburetor and seems to do a great job on stock/ near-stock 260/ 289's!! Factory refurbs are typically <$300 bucks!

Be careful on intake choice. Many of the more modern intakes were made to better fit the later SBF heads that used larger intake ports! They will overlap on 260/ 289 stuff!!

So which manufactured intake would be the best one to use. Just don't want to take 2 steps back thinking I'm moving forward.

[CALIFORNIA CALIENTE]

Intake manifold selection can be tough! If it is a very mild 289 used mostly for a nice cruizer then a dual plane intake is best,gives good cylinder to cylinder flow,works from idle to usually a lower max RPM.I use an Edelbrock RPM-Airgap dual plane with a vacuum secondary Holley 600 cfm,idles and runs great! I have used the Edelbrock Performer RPM dual plane with great driveability on a 289 with a Holley 600CFM Vacuum secondary,very mild daily driver with a C-4 auto in a 65 Comet 404 two door sedan! Which ever manifold you use,try to find one with smaller port sizes and a dual plane configuration! I have used these examples as they are real world useages,NOT from a book!! ROY.

[oldhot65]

Thank you Roy very helpful. Looks like I've got some comparing to do

[oldhot65]

Ok called around local junk yards, parts for this year 1965 are a hard find mostly just gone. Looked on eBay found a 2121 edelbrock and another off a mustang 289 cast iron intake don't really want to take the chance on new because of port size differences which are not in description. Wish it was spring time I would be able to go further out for parts.

[CALIFORNIA CALIENTE]

Both manifolds I listed fit stock ports as both engines are mostly stock!! ROY.

Hi, Here's the set-up that will make you smile... Guaranteed!

I visited my Father-in-law over Christmas and he showed me his new "toy". He had purchased a '65 Sunbeam Tiger. FYI a Sunbeam Tiger is a British sports car with a FORD 260 and then a 289 V-8 stuffed in it. The engine package was designed with help from Shelby. The car ran so much better than my Edelbrock 500 cfm Performer on top of a Performer 289 intake with a Performer cam.

What I'm saying is forget the Edelbrock carb idea, Go with a Holley 0-1848-1 vaccum secondary 465cfm 4bbl carb with the Edelbrock Performer 289 intake and a Edelbrock Performer cam set-up.

Why do I say this? Shelby got together in the mid '60s to design an "super induction" system for the Sunbeam Tiger call the LAT 1 package. It consisted of a Holley 0-1848-1 465 cfm 4bbl carb, the Edelbrock 4FB intake manifold and a mild cam. Here is the info on the induction package...

Why this set-up? I just finished putting this carb on my 260 with a Performer Intake and a Performer cam and the car runs $^*(%^^%(%$ Perfect. SO much better thatn the 500 cfm Edelbrock Performer carb with all their screwed up tune up spring and jet set. Out of the box this thing is perfect. Here's the carb info from Holley. I got one open box for $320.00 from Summit (sharksmotorsports) on ebay.

Since Carrol Shelby designed this induction system for the 260/289 V-8's, I would trust his expertise over all our buds here. (and they're good)

If you still want to go with a Edelbrock, I'll sell you the one I just took off with the tune up kit. I would stay away from the finicky, rich running Edelbrock.
