I still think that RPM manifold is overkill for stock 093 heads.

In full agreement with post 21 besides having real world on the road daily driver experience with it.

If that’s not enough for the OP then here are Edelbrocks own recommendations.

Cardo post #2 and b-man post #15 and both correct IMO. An original AFB from the era of your car is the most reliable and trouble free four barrel route you can go. Holley or quadrajet carbs can be made to outperform an afb but can both be real PITA if not set up right in the first place and both take more expertise than does the afb to get set up. The same applies to the tripower setup with the added criticisms that it is the system most likely to get out of whack down the road, the carbs themselves have several engineering flaws, and sets have the most fuel connestions so are the most likely to catch fire. But trips ARE sexy as b-man says. If you want reliability and sex appeal both go with dual quad afbs on an offenhauser intake.

You could go the opposite of the "Coolness" of a tripower and use an O.E. cast iron Q-Jet intake with a real Q-Jet, then wait for all the Quadrajunk comments. Of course this "might" be the best performing combination...LOL

The fact you did not specify is YOUR desire:

(1) eye candy (tripower or dual AFB's)
(2) street performance with a basically stock engine (single AFB, dual AFB, Q-Jet)
(3) win the bench "my engine makes more HP than your engine" race (dual AFB, Holley, Q-Jet)

Footnote: All AFB references above are to genuine Carter AFB's.

Once you have answered the above question to YOUR satisfaction, the choice of an intake manifold becomes fairly obvious.

Jon, you're absolutely right, I should have been more specific. My 65 build is going to be a weekend cruiser which fits # (2) street performance with a basically stock engine (single AFB, dual AFB, Q-Jet). Thanks.

What manifold or manifolds do you currently own? If you own a stock 65 4bbl intake that should help make the decision a little easier.

The first criteria in making a happy customer is to listen to the customer!

I have an Edelbrock Performer, a 69 iron 4bbl intake and a 66 Tripower intake. I think I'm going to use the 69 intake for now and once the car is out of the shop (Body & Paint), I'll install the tri-power.

Do you have a proven QJ for the 69 intake?Tom

Stick with the Performer RPM and the 650 Holley. The 650 is not too small at all. Its about the perfect size. Ive done a lot of dragstrip testing with different sized carbs and different sized motors and was shocked to find that going smaller on the carb than conventional thinking implies, resulted in quicker ET,s. BTW my testing proved to me without a doubt that a properly sized Holley 4150 was always quicker than a Q-jet. Several other racers that I know came to the same conclusion. They just don't post here.

He does not have a Performer rpm to stick with as is recommended in post 35, he has a Performer and a iron intake .

The regular Performer worked great on a 400 I was testing back in 90,s. It was a 79 T/A with a 400 and ran the quickest time with a Performer and a Holley 600 DP. It ran a 14.2 with the factory intake and Q-jet. Changing to a Performer and a 600 DP it went 13.8. I tried a 800 DP and the car slowed to 14.0.
They say the Performer doesn't work on 455,s. I don't know because I never tested one on a 455 but I can say for sure they work great on a 400 which is basically the same as a 389.

Performer for the street. Has better bottom end torque than RPM. Less weight and better heat dissipation than Iron. Holley Street HP 750 on a 1” phenolic wood spacer. No choke. Mechanical secondary. You’ll have to feather the throttle to keep it alive for the first 20 seconds. Guarantee you’ll be in the zone on air fuel mixture out of the box and it will be snappy and not run out of fuel on the back end of a hard run. New polished aluminum body helps keep fuel from flashing over and vapor locking. Looks and runs fantastic. Best all around combo I’ve come up with in 40 years.
