Unlike the later, second-generation 427, it was based on the W-series 409 engine, but with a longer 3.65 in (92.7 mm) stroke. A high-rise, two-piece aluminum intake manifold and dual Carter AFB carburetors fed a 13.5:1 compression ratio to produce an under-rated SAE gross 430 hp (321 kW) and 575 lb⋅ft (780 N⋅m).
Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston 's movement on the induction stroke and the airflow through a throttle in the intervening carburetor or throttle body leading to the intake manifold.
These companies include: Weiand (intake manifolds and superchargers), B&M's supercharger division, Hooker Headers, Earl's Performance Plumbing, Flow Tech exhaust, Lunati (camshafts, crankshafts, pistons and connecting rods), NOS (Nitrous Oxide Systems, Inc), and So-Cal Speed Shop, as well as a few ancillary companies.
The big bore allowed for larger, 2.08 in (53 mm), intake valves, and the relatively short stroke helped it to be a free-revving and free-breathing engine. Producing a maximum of 330 hp (246 kW; 335 PS) and 460 lb⋅ft (624 N⋅m) of torque for the 1960 model year, the 383 beat the 392 Hemi that had reached 435 lb⋅ft (590 N⋅m).
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
It offers the airflow of more expensive heads, at a much lower cost. It does, however, require a specific intake manifold (the L31 has four bolts per head attaching the intake manifold, as opposed to the "traditional" six bolts per head found on older Chevrolet small-blocks). Chevrolet's L31 was replaced by GM's LS-based 5.3L LM7 and 6.0L LQ4.
The Cadillac 331 engine featured a "dry" (coolant exited through an assembly attached directly to the cylinder heads), open runner (requiring the use of a tappet valve cover) intake manifold, rear-mounted distributor, and shaft-mounted rockers. Crankshaft end play is carried by the rear bearing on the two GM engines.
Ford — Dual-Stage Intake (DSI), on their Duratec 2.5 and 3.0-litre V6s, and it was also found on the Yamaha V6 in the Taurus SHO. The Ford Modular V8 engines and the V6 Cologne use either the Intake Manifold Runner Control (IMRC) for four-valve engines, or the Charge Motion Control Valve (CMCV) for three-valve engines.
