Chevy Small-block—1962 to 1998 Number 7

The 4.0-inch bore 350 variations 1967 to 1980 continued…

For the 1969 and the 1970 model years, the L46 was an option for the Corvette; this is a high-performance version of the base 350 engine. Its block casting number is 492, and it features 2.2/1.60-inch valve heads and has a high 11:1 compression ratio delivering 350 bhp (261 kW).

The LT-1 350 for the Corvette in 1970 was the pinnacle for this small-block. Solid lifters, a high 11.1:1 compression, a high output “178” crank, topped off with a CFM Holley carburetor on the aluminum intake and the rams’ horn manifold handling the low restriction exhaust, worked together to give it the edge. The Delco transistorized ignition allows the LT-1 to put out 370 bhp (272.1 kW) in the Corvette and 360 bhp (264.8 kW) in the Camaro Z/28 at 6000 rpm developing 380 lbs-ft. of torque at 4000 rpm, but the NHRA rated this engine at 425hp (312.6 kW). The LT-1 red lined at 6500 rpm, but the power begins to drop off at 6300 rpm. For 1971, this 350 engine has the compression dropped to 9:1, which now allowed the LT-1, in both the Vette and the Camaro, to develop 330 bhp (255 net hp; 242.7 kW) with a further drop in 1972 to 255 bhp and producing 360 lbs.-ft. of torque. Note in ’72, a “net” figure is used and not a “gross” measurement. The 350 LT-1 went on a 19-year hiatus but returned in 1991 as a small-block engine in the generation II.

1973 until 1980 the 350 L82

For the ’73 and ’74 models years, Chevy marketed the L82 as a performance 350 producing 250 hp (183.88 kW) with 285 lbs.-ft. of torque from the factory; this was an SAE net hp rating now. The 2.02 heads have a 76cc chamber size with the 624 casting number imprinted. The carburetor is the Rochester Quadra-jet four barrel bolted to the dual plane aluminum manifold, with the same hydraulic lifter cam as the earlier L46, and forged aluminum pistons with a 9:1 compression. The factory delivered these engines with crinkle black rocker covers with the distributor housing and the manifolds aluminum-colored. The Corvette in 1975 delivered 210 bhp (154.45 kW), but other models put out 205 bhp (150.78 kW) and developed 255 lbs.-ft. of torque. These figures remained the same through ’77, but in 1978, the Corvette L82 was slightly up and developed 220 bhp (161,8 kW) offering 260 lbs.-ft. of torque. For the ’79 model, the L82 350 engine 225 bhp (165.49 kW) for the last year, 1980, reached the high point of 230 bhp (169,17 kW).  This same engine was also available for the Camaro.

The only year for the L81 version of the 350 was 1981 and was the only 5.7-liter engine in the Corvette for that year. The compression is 8.2:1 and with the high-performance cam working with the computer-controlled spark advance distributor, this version developed 190 bhp (139,73 kW) and produced 280 lbs.-ft. of torque. The “smart” carburetor made the L81 a one-of-a-kind. The Rochester Quadra-jet was altered to allow the fuel mixture to be controlled electronically; a sensor in the exhaust manifold feeds data to the Engine Control Module (ECM), altering the fuel/air mixture to meet demand.

1948 Cadillac Ambulance pulled from yard Also 58 Ford Skyliner ...

Comment on Facebook

Streamlined roof-mounted emergency lighting pods were beginning to appear by 1940 and Meteor showed a number of ambulances so-equipped in their mailings. Meteor's flower cars were topped by 5-window business coupe-style roofs and featured a fake folded convertible top made of aluminum mounted at the rear of the flower box. Meteor introduced a new driver's door first seen on 1939 S&S carved-panel coaches that featured an unusual A-shaped window frame. Meteor then mounted a miniature coach lamp within the triangular panel that was now part of the body. Although the new arched door looked great on their service cars, flower cars and carved Gothic hearses, it looked hideous when combined with the vertical B & C pillars found on their limousine-style coaches and ambulances. The rear door window frames as well as the B-pillars and C-pillars were still vertically oriented and clashed with the sharply sloping outline of the front door's arched window-frame.S&S did the right thing and used vertical B-pillar front door frames on their regular limousine-style and landau-style hearses and ambulances. Although they could have used a regular door on their limousine-style coaches and ambulances (as did S&S), for some unknown reason, Meteor didn't and continued producing ugly limousine style coaches until 1950, when regular door frames returned.Quite unfairly, LaSalle had acquired the reputation of being a "cheap" Cadillac and was eliminated by GM just as Cadillac released their new Bill Mitchell-designed models in 1941. The new Cadillac was decidedly forward-looking, side-mounted spares had been eliminated and the new Hydra-Matic automatic transmission was available for the first time having been pioneered by Oldsmobile in the previous year. The prow-nosed look seen in the Thirties was gone, replaced by massive front-end highlighted by the now-famous egg-crate grille. Headlamps were now mounted in, rather than on top of, the front fenders. Equipped with a Cord-like coffin-nose hood the new Cadillacs were noticeably different from their predecessors and set the standard for American luxury during the 1940s. A mid-sized 29-passenger transit bus prototype called the 101 was built during 1941, but never saw production. However their experience with the vehicle helped procure a large contract to produce bodies for a post-war Reo transit coach.The A-framed Meteor coaches continued little unchanged through 1942 although a less-expensive series of coaches appeared in 1941 mounted on Chevrolet chassis that featured normal-looking vertically-oriented B-pillars. When seen on a flower car body, Meteor's A-framed front doors looked good and their 1942 version featured a 5-window business coupe roof mounted on top of a standard Meteor coach body that had been built with no structure above the beltline. The coupe's blanked-in rear quarter-windows were covered by a landau bar and the base of the roof flowed straight back to the rear of the flower box which still had a makeshift faux folded-convertible roof. The rear doors were left intact and could be used to load chairs or other graveside necessities. Access to the casket compartment was through the tailgate which had built-in casket rollers that matched those on the compartment floor. The height of the exposed stainless steel flower deck was hydraulically adjustable so that different-sized floral tributes could be accommodated and a tonneau was included to cover the bed when not in use.After an illustrious career with Henney and a short stint at the Des Moines Casket Company, automotive designer Herman Earl (1878-1957) worked for Meteor up until his retirement during WWII. Another famous wartime Meteor employee was John B. Judkins who became a consultant for the firm, when his Merrimac, MA coachbuilding firm folded in 1942. During the War, Meteor manufactured aviation equipment for the US Navy and ramped up for civilian production in early 1945.Immediately after the war Meteor built 969 bus bodies for Reo's post-war 96-HT 'Victory' bus (1945-1947). These Reo-Meteor coaches included a Continental 427cu in 6­cylinder gasoline engine mounted under the floor and featured sectional bodies similar to those produced by Wayne Works.1946-1948 Meteor coaches remained unchanged from the pre-war 1942 models and still included weird A-framed front doors with integral miniature coach lamps. As with other makers, post-war prices increased by about 50% and new Meteor coaches started at $5,000. All Meteor coaches were now built on Cadillac chassis and included rear fender skirts plus optional automatic transmission and air-conditioning. Ambulances could be ordered with built-in roof-top warning lights, a choice of sirens plus a clever front fender-mounted fire extinguisher.Cadillac's new commercial chassis was available beginning 1949, one year after the introduction of their famous P-38 Lightning-influenced rear fenders.
