From self-learning EFI systems to wireless data loggers, the technology in our hot rodding industry is definitely on the incline. Even the lifebloods of our street machines are becoming more advanced. Companies like AFCO, Flex-a-lite, COMP Cams, Joe Gibbs’ Driven, and TCI Auto have come up with additives and oils that are designed with high performance in mind. Cooling system additives make our aluminum parts live longer, pump-gas additives make our carburetors run cleaner and leak-free, and highly durable engine and transmission fluids make our hot rods run better and longer. With our Nova back from O.C. Muffler Man, we began the plumbing process, which included running the fuel and oil lines to a remote transmission cooler and adding the precious fluids that will bring our monster to life.
Plumbing the car for fuel and transmission hoses is one of our favorite steps in a build because you have the opportunity to lay everything out nice and tidy. We decided to run steel braided lines under the car due to its durability and black braided hose under the hood to connect to the carb and fuel pressure regulator. We contacted the fuel system experts at Aeromotive for their tried-and-true A1000 fuel pump, return-style pressure regulator, fuel lines, and all the hose ends and fittings (in black) needed to feed our street demon. For the transmission cooler, we contacted Derale for one of their latest stacked, dual-fan oil coolers. Our engine cooling system consists of a Moroso electric water pump and a Flex-a-lite universal radiator/fan combo.
Since the Hellion is a street car, it’ll be sipping on California’s 91-octane pump swill. However, we do plan on running 100-octane at the track. The engine was tuned at Westech Performance Group to make over 500 horsepower on 91, but we suspect the engine will like the higher octane gas due to its 10.65:1 compression. Joe Gibbs’ Driven Carb Defender is something we just learned about and will be running in the Nova’s fuel system as well. Since the ethanol-heavy gasoline in the pumps these days are only tested on fuel injected engines, carburetors are left in the dark and these new fuels can wreak havoc on the carb’s seals over time. Carb Defender prevents that without affecting the octane rating.
Companies such as Speedway Motors and Summit Racing were also instrumental in getting these systems operational. Summit offers an affordable 20-gallon fuel cell and brackets, while Speedway was a great source for custom radiator hoses.
Over the following pages we’ll show off some of the products we used to route our Nova’s ever-important fluids to the necessary areas. After a few more build-up articles where we highlight some of the other aspects of our car, you can expect us to put this Chevy II combination to the test at the dragstrip. Stay tuned.
Underside PrepBefore we ran our fuel and transmission lines, we spent some time cleaning and degreasing the underside of the car. While being a tremendously filthy job, it’s well worth it once it’s all clean. To finish up, we shot the undercarriage with Eastwood’s Chassis Black paint.
Aeromotive’s A1000 pump has been used on street machines for a long time and can feed up to 1,300 horsepower, naturally aspirated. Other features include ORB-10 outlets, anodized red case, and internals that are designed for daily drivers, yet can feed the most radical engines.
Summit Racing offers quite a few aluminum fuel cells, including the 20-gallon version we ordered (PN SUM-291220D). It comes sumped with two AN-8 male fittings, a return, and a place for the vent.
Aeromotive required us to switch to a larger AN-10 fitting to feed the pump. This way it will be fed with an ample amount of fuel at all times. To convert the cell we removed the foam, drilled the hole (making sure to vacuum out the debris) and installed an AN-10 bulkhead fitting.
Once the AN-10 outlet was in place, we attached the A1000 pump to the trunk floor. We were able to run the AN-10 size to the pump and about halfway up the bottom of the car before we converted down to AN-8. The return line was also done in AN-8. You can also see our dual Optima RedTops, which power the beast.
A photo under the car shows how we ran the fuel lines. We used rubberized Adel clamps to hold the lines in place. This system requires a return line to keep the pump cool and improve the life of the pump.
Aeromotive’s return-style regulator (PN 13204) was mounted to the passenger-side inner fender. We used Earl’s color-coded AN wrenches to put the entire system together.
Our TCI Automotive Turbo 400 Super Street Fighter trans received TCI’s Max Shift fluid for the ultimate in durability. This stuff is specifically engineered with high performance in mind and has superior properties compared to parts store fluid.
Lokar’s Locking Dipstick was also ordered for the Nova, which we thought was a very trick piece. Being NHRA approved means it’s accepted at race tracks and its locking mechanism ensures the stick won’t come flying out for any reason. To install this piece correctly, the transmission oil pan must be removed.
