1969 Chevrolet Camaro Aluminum ZL1 Ram Jet 454 Build Project
Power:
A career Chevrolet dealer, Paul got the inside track on a very special engine: one of the aluminum ZL1s reissued by Chevrolet. Paul’s is number 35 of the 200 Ram Jets. Knowing the engine would have to fill big shoes GM stroked the crank to 4 inches to achieve 454 cubes. It swings a set of forged 4.25-inch pistons by way of shot-peened I-beam connecting rods. The displacement, when combined with the 110cc chambers in the oval-port heads, yields a 10.2:1 compression ratio. That’s two points less than the original ZL1 figure, but when combined with a mechanical-roller-tappet camshaft that pops valves open 0.640 and 0.598 inch and keeps ’em there for 236 and 232 degrees (at 0.050 inch) it’s worth 493 lb-ft torque at 4,250 rpm and 510 hp at 5,750-on today’s pump gasoline no less. Call that impossible with the original. Another piece to the pump-gas puzzle is the Ram Jet injection system that administers just the right amount of cool, atomized fuel just when each cylinder needs it. To maintain the engine’s cool, DSE recruited a pair of 11-inch SPAL electric fans on a Be Cool alloy radiator. Driving it is the 140-amp alternator on the Vintage Air front runner accessory drive system. DSE fabricated the housing for the K&N filter element. It also made the 2-inch primary headers. Those feed 3-inch diameter stainless pipes configured with an X and damped with a pair of Borla XR1 mufflers. Between those pipes is a Tremec T56 six-speed transmission with special overdrive ratios. It couples to the engine via a Centerforce clutch.
Outside:
The ’69 Paul found led a relatively pampered life, including a few years as a dealer’s wife’s car. He removed the few unnecessary articles before shipping it to Detroit Speed. With painstaking attention to preserve the body’s integrity, DSE widened the rear wheeltubs to fit the wider rear hides. It also flattened the firewall for a cleaner appearance and fabricated numerous engine compartment elements, like the flared-hole radiator support and air filter housing. The tall intake manifold required a cowl-induction hood that DSE artfully modified by filling the inner structure with flat sheet and opening it to match the plenum’s shape. A set of billet DSE hinges replaces the stamped-steel ones, and braided lines routed over the passenger fenderwell transfer coolant and refrigerant to the Vintage Air climate-control system. Even the car’s underside received the same level of detail. For example, DSE rerouted the parking brake cables above the floor and filleted the tubing where it passed through the metal. Externally the car remains faithful to the original; the only differences being High Intensity Discharge headlights, show car panel fit and finish, and DuPont Hot Hues-blended red urethane paint.
Rollers & Stoppers:
The Budnik Famosa wheels Paul called on somewhat reflect traditional five-spoke designs, albeit in billet form. The front wheels measure 17x8, and due to their 4.875-inch backspace, the Michelin Pilot Sport 245/40YR17s tuck magically. The rear wheels measure 17x12 with a 5.5-inch backspace and wear 335/35YR17s. Those wheels sandwich a set of Baer Track 4 series 13-inch cross-drilled and slotted rotors. A 9-inch booster behind a Raybestos dual-circuit master cylinder puts the pressure on four-piston Baer calipers.
Bones:
Just because Detroit Speed retained the stock front crossmember doesn’t mean it didn’t modify the suspension. It updated the front with its tubular control arms, spindles, antiroll bar, and prepped Koni aluminum-bodied coilover dampers. A modified Saginaw 600-series fast-ratio steering box replaced the original. Detroit Speed retained the rear leaf springs, albeit with flatter plates for a lower stance and DSE-prepped Koni dampers. Bolted to those springs is a 9-inch Ford housing with a 3.77:1 gear bolted to an Eaton Truetrac limited-slip carrier. It spins 31-spline axles.

Nice tribute with the 'hounds tooth' seat pattern
