The Flash says: “You can shop ‘til you drop when it comes to fuel systems for the big Caddy, Or you can call Cad Company and get everything, including a high performance mechanical fuel pump, with one call.
Intake Manifolds
Please check hood clearance before ordering.
Most aftermarket intakes raise the carb 4”-5” over stock height.
Cad Company PRO/Cad III Ported Aluminum Dual Plane Intake $350.00
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.
Edelbrock 2115 cast hi rise manifold $299
(less effective at low RPMs, less $$)
Cad Company PRO/Cad IV Dual Plane Dominator Intake $550.00
Use where performance gains in mid-range and top end (to 6800) are the most important,
but a dual plane intake is still desired. The PC-IV features a large plenum for Dominator carburetor,
intake ports raised and widened for competition cylinder heads.
Single Plane Intake
Available with standard or Dominator carb flange.
Cast-in injector bungs for fuel injection (or port-nitrous).
Options include pre-drilled injector bungs, fuel rail setups, etc.
Standard square bore (4150) style $459
Dominator style $479
Cast Tunnel Ram - Low Profile $595
Does not include carb adapter (from $75)
Large plenum, short runner competition intake. The hot ticket for running multiple carbs and high RPM. Available with cast or CNC carb adapters for various applications (i.e. single or dual 4bbl or Dominator, 3X2, etc).
Blower Kit When cubic inches aren’t enough @ $5600
Complete with Intake, 8-71 blower plate, BDS 8-71 Blower, dual carb adapter, tensioner, belt, blower drive, billet steel crank hub, and accessory drive crank pulleys.
Makes ~ 8 PSI on most non-strokers at 1:1 drive.
For Stage II blower, add $200 for 10 PSI (500 CID) or 8 PSI (strokers) at 1:1 drive ratio.
Polishing, carbs, linkages, plumbing, and bigger blowers are also available.
Kit components available separately. We do not recommend running blowers smaller than 8-71.
Vintage Style 4-Deuce Intake $550 Specify Carb flange style.
Fabricated steel twin-log style intake with balance tube, 2 carbs flanges on each side.
Want 6 or 8 (or more) carbs? Add more carb flanges for $100 / pair.
Also available in kit form starting at $300.
Composite Intake Gaskets for aluminum intakes $20
Socket Head (Allen) Intake Bolt Kits $20 black, $35 Stainless Steel
EGR Block Off for OE intakes, billet aluminum $25.00
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.
OE Replacement Pump $65
w/ or w/o return line fitting
High Perf Mechanical Fuel Pump $159.00 Chrome, rated at 80 GPH
Racing Mechanical Fuel Pump $350 Supports up to 1100 HP
Adjustable Fuel Pressure Regulator $49
Strongly recommended w/ Performance Pump
W/ dual outlets for double pumpers or for running a pressure gauge
Billet Steel Fuel Pump Eccentric $40
Billet Aluminum Fuel Pump Block Off $20
Air Cleaners

We also offer a variety of other styles of air cleaners. Call for more information.
Carburetors
Q-Jet $395
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 or Chevy 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.
Q-jet Tuning Kit $59
If you’ve modified your engine - cam, intake, etc - we’ve found a substantial power gain can be had by re-calibrating the carb. This combination of jets, metering rods, and hangers will get you in the right range!
This is also a good starting point if your carb is way off due to previous tuning efforts.
Q-jet Rebuild Kit - gaskets, acc. pump, etc $35
Please specify carb number when ordering.
Holley Street Avenger 870 $550
Well suited for street applications in the +150 to +300 HP range. Features include electric choke, vacuum secondaries, legendary Holley tunability, and great looks.
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.
