Intake Manifolds

Please check hood clearance before ordering.
Most aftermarket intakes raise the carb 4”-5” over stock height.

Edelbrock IntakeCad Company PRO/Cad™ III AF72215 Ported Aluminum Dual Plane Intake
Use where performance gains in bottom end and mid-range (to 5500) are desired. Most effective when used with ported or aluminum cylinder heads. See gaskets and bolts below. This intake will raise your carb roughly 4″ above stock. Made in USA
Edelbrock™ 2115 AF72115 cast hi rise manifold
(less effective at low RPMs, less $$) This intake will raise your carb roughly 4″ above stock.

Single Plane IntakeSmall Single Plane Intake AF71105
Available with standard or Dominator carb flange.
This is the old Bulldog™ style intake. Cast-in injector bungs for fuel injection (or port-nitrous) as available, but no gaurantees on whether they will work with your setup.
Options include pre-drilled injector bungs, fuel rail setups, etc. This intake will raise your carb roughly 4″ above stock.

Standard square bore (4150) style
Dominator style

Cast Tunnel Ram IntakeBoogieMan™ Single Plane Intake AF71475
This is the king of the hill when it comes to single carb intakes.
Currently only available with the Dominator style carb flange. All intakes have full sized injector bungs, with plenty of room for most styles of injectors. This intake will raise your carb quite a bit more than 4″ higher than stock. Made in USA.

 

Cast Tunnel Ram IntakeBM1480 BoogieMan™ Tunnel Ram AF71480
Does not include top plate. Large plenum, short runner competition intake. Great for blowers or the hot ticket for running multiple carbs and high RPM. Cast-in injector bungs. Made in USA
Note: We do not offer top plates or other individual blower kit components at this time.
This intake is for people who want a modular setup to make their own configuration.
If you are building a blower combo, we recommend buying a complete blower kit made up of matched components.

Engine with blowerBlower Kit When cubic inches aren’t enough $call
Complete with Intake, blower plate, 8-71 (or bigger) Blower, carb adapter as appropriate, tensioner, belt, blower drive, billet steel crank hub, and accessory drive pulleys (as needed).
A standard 8-71 blower makes ~ 8 PSI on most street performance non-strokers at 1:1 drive.

Blower kits are specced and priced per application.
Kit components available separately. We do not recommend running blowers smaller than 8-71.

Fuel Pumps

When it comes to fuel pumps, there is no such thing as too much capacity. During testing, we found that on even medium level street engines, well under 400 HP, fuel pressure supplied by the standard ‘high flow’ replacement pump dropped off to the point of having to stop the pull less than halfway through as the carb’s fuel bowl was emptied, resulting in detonation. Note that these pulls were only 8 seconds at WOT, and most hot rods see more extended periods of WOT than that…

The other consideration is too much pressure – Cad Company’s High Performance fuel pumps tend to generate enough pressure to unseat the needle valve during pressure spikes, such as sudden deceleration, causing a flooded engine. Running a High Performance pump on any engine without a pressure regulator is strongly discouraged. Note that these pressure spikes could cause a ruptured fuel pump diaphragm in some cases, with or without a pressure regulator, without a return line installed. A return line will also greatly reduce the chance of vapor lock.

Carburetors

Remanufactured Q-JetQ-Jet AF12010 oe AF12210
This is a ‘Stage 1.5’ Quadrajet, completely remanufactured from an original Rochester core to keep the reliability and economy. These carburetors feature upgrades such as bushed throttle shafts, modified air bleeds, and more.
They are tuned to our specs based on the dyno testing outlined in the Dyno Results on pages 5-7. Ideal for engines from stock to +250 HP.
Available with Cadillac (AF12010) or Chevy (AF12210) style throttle linkage. Cadillac style carbs are available with electric or divorced chokes (heat operated choke actuator not included). Please verify manifold and linkage compatibility before ordering. Made in USA

Street Demon 625 CFM AF12510
Well suited for street applications for 331, 365, 390, and 429 CID engines with square bore or 4-jet (pre-’67) style intake manifolds. Features include electric choke, vacuum secondaries, and great looks. Solid 1-piece upper / lower throttle arm makes hooking up ’66-older reverse operation throttle linkages (relatively) easy. ‘Goggle valve’ (oval) secondary provides spread-bore-like bottom end torque, drivability, and MPG, in a carb compatible with non-spread-bore intake manifolds
Comes standard in ball-burnished aluminum finish. Polished finish available for additional charge. Ploy fuel bowl also available for an additional charge.

Street Demon 750 CFM AF12520

High Performance Carburetors
While the carburetors above are generally the best bet for most street engines, we carry a variety of other carburetors to suit every need. From the basics such as Edelbrock, Holley, Holley Dominators, and Demons to high end gas or alcohol carburetors such as those from C&S, and Quick Fuel Technologies.
