Firebirds and Camaros because it was the only engine that offered a 5 speed manual combination. The 350 exceeded the Borg-Warner T5's input power ratings, and as such, it was cut from the 350 cars to prevent lemon law and warranty losses. The L03 used hydraulic roller lifters, which allowed it to recover some of the lost horsepower from its factory design, while further increasing efficiency (reduced rotational drag). Despite downfalls in its aspiration restrictions, the L03 had one thing going for it: reliability (87-90 F-bodies that carry the L03 did not use a rev limiter). They used dished pistons with a 9.3:1 to 9.5:1 compression ratio The L03 TBI featured a 3.736" bore and 3.48" stroke, the same as its TPI cousin, the LB9. L30 Years: 1996-2003 The Vortec 5000 L30 is a V8 truck engine. Displacement is 5,020 cc, (305.4 cubic inches). Bore is , stroke is . The compression ratio is 9.1:1. It is based on the Generation I small-block from Chevrolet. It was replaced by the 4.8 L Vortec 4800 LR4 for the 2003 full-size vans. In C/K truck configuration it produces net flywheel at 4,600 rpm and net flywheel torque at 2,800 rpm. In van configuration it produces net flywheel at 4,600 rpm and net flywheel torque at 2,800 rpm. The engine uses a hydraulic roller cam and high flowing, fast burn style vortec heads. Differences include bore and stroke, intake valve size, and smaller combustion chambers. L30 applications: Chevrolet Express/GMC Savana General Motors C/K full-size trucks 3.50 in bore family (1979–1982) 267 The 267 was introduced in 1979 for GM F-body (Camaro), G-bodies (Chevrolet Monte Carlo, El Camino, and Malibu Classic) and also used on GM B-body cars (Impala and Caprice models). The engine had the 350's crankshaft stroke of and the smallest bore of any small-block, , shared with the 200 V6 introduced a year earlier. It was only available with a M2ME Rochester Dualjet 210 – effectively a Rochester Quadrajet with no rear barrels. After 1980, electronic feedback carburetion was used on the 267. The 267 also saw use in 1980 to 1982 Checker Marathons. While similar in displacement to the other V8 engines produced by General Motors (including the Oldsmobile 260 and Pontiac 265), the small bore 267 shared no parts with the other engines and was phased out after the 1982 model year due to inability to conform to emission
