Hangt er al vanaf welke AMC V8... En dan zijn er nog aanmerkelijke verschillen in bouwjaar!

In de CJ 5 en CJ 7 werd, af fabriek, de "304" geleverd:

Specs:

The AMC 304 uses a cast iron block and heads with over head valves and hydraulic lifters. The AMC 304 was introduced in Jeep vehicles in 1971 in J-series pickups and Wagoneers and in 1972 in the CJ vehicles. Early 304s performed well, so well that frame changes were made to the CJs in '73 to prevent cracks. Meeting legal requirements for smog controls on the 304 severely hurt performance of the engine. The last two years of the 304 in the CJ were in '80-'81. The horse power and torque specifications of the last version of the 304 narrowly beat the 258 use at this time. The 258 used between '80 and '81 was putting out 110 HP @ 3500 and 195 ft/lbs @ 2000.

The 304 used from '80-'81 in CJs, J-series pickups, and Wagoneers suffers in performance.

The 304 used from '72-'78 has the best performance of all the 304s used in the CJ. The 304 was not offered in J-series pickups and Wagoneers after 1972.

De Chevy heeft ook per bouwjaar verschillende vermogens / koppelkromme's:

The first generation of Chevrolet small-blocks began with the 1955 Chevrolet 265 in³ (4.3 L) V8. But it was the 350 in³ (5.7L) series that set the standard for high performance. The engine's physical dimensions (oversquare 4.00 in bore and 3.48 in stroke, 102 mm by 88 mm) are nearly identical to the 400 hp (300 kW) LS2 engine of today, but of course much has changed. It is by far the most widely used Chevrolet small-block; from the factory, it was installed in everything from station wagons to sports cars to heavy trucks.

A 350 is usually common with engine swaps - much of the older, pre-1968 Chevrolet V8s were usually swapped with a later 350 when engine replacement was the norm. It has been known to swap a 350 in place of a 305 since the 350 is part of the same engine family (the external dimensions of a Chevrolet small block are the same).

First usage of the 350 was in the 1967 Chevrolet Camaro and 1968 Nova producing 295 horsepower (gross); other Chevrolet vehicle lines followed suit in the year 1969.

The GM Goodwrench 350 crate motor (sold through Chevrolet dealerships) is based on the pre-1986 small block design with two dipstick locations; pre-1980 on the passenger's side and post-1980 on the driver's side. This motor was produced in Mexico since 1981 as the Targetmaster 350.

Note that Oldsmobile produced an entirely different 350 in³ V8 (4.057 in bore and 3.53 in stroke, 103 mm by 90 mm), the L34 and LF9 from the 1980s.

[edit] ZQ3

Years: 1969, 1970, 1972-1975

The ZQ3 was the standard engine in the 1969-1970 Chevrolet Corvette. It was a 300 hp (224 kW) version of the 350 in³ (5.7 L) small-block, with 10.25:1 compression and hydraulic lifters. It used a Rochester "4MV" Quadra-Jet 4-barrel carburetor. This was the first block produced that featured the larger 2.45 inch main bearing versus the older 2.30 inch main bearing in 1968/1969.

The 1972 ZQ3 produced 200 hp (150 kW) and 300 ft·lbf (407 N·m) with 8.5:1 compression, dropping another 10 hp (7.5 kW) in 1973. 1975 saw the ZQ3 at 165 hp (123 kW) and 255 ft·lbf (346 N·m).

[edit] L46

Years: 1969, 1970

The L46 was an optional engine on the 1969-1970 Chevrolet Corvette. It was a 350 hp (261 kW), 380 ft·lbf (515 N·m) version of the ZQ3 with higher 11:1 compression.

[edit] LT-1

Years: 1970-1972

The LT-1 was the ultimate 350 V8, becoming available in 1970. It used solid lifters, 11:1 compression, a high-performance camshaft, and a Holley four-barrel carburetor on a special aluminum intake to produce 370 hp (276 kW) and 380 ft·lbf (515 N·m). It was available on the Corvette and Camaro Z28. Power was down in 1971 to 330 hp (246 kW) and 360 ft·lbf (477 N·m) with 9:1 compression, and again in 1972 (the last year of the LT-1) to 255 hp (190 kW) and 280 ft·lbf (380 N·m).

Note that there was a later small-block engine called the "LT1".

[edit] L48

Years: 1970-1980

The L48 was the standard engine on the 1971 Chevrolet Corvette. It produced 270 hp (201 kW) and 360 ft·lbf (477 N·m) with an 8.5:1 compression ratio.

The 1976-1979 L48 was the standard Corvette engine and produced 180 hp (134 kW) and 270 ft·lbf (366 N·m). The 1980 L48 stood at 190 hp (142 kW) and 280 ft·lbf (380 N·m) from 8.2:1 compression.

In 1973 the "L-48" had cold air induction (throttle activated) and developed 190 hp (net). Beginning in 1974 the hp was reduced for several years until it reached a low of 165 (net) in 1975 or '76, before rising again.

[edit] L82

Years: 1973-1980

The 1973-1974 L82 was a performance version of the 350 producing 250 hp (186 kW) and 285 ft·lbf (386 N·m) from 9:1 compression. It was down to 205 hp (153 kW) and 255 ft·lbf (346 N·m) for 1975. It was the optional engine again in 1976-1977, producing 5 hp (4 kW) more. The 1978 L82 recovered somewhat, producing 220 hp (164 kW) and 260 ft·lbf (353 N·m), and 5 hp (4 kW) and 10 ft·lbf (14 N·m) more for 1979. 1980 saw another 10 hp (7.5 kW) and 15 ft·lbf (20 N·m).

[edit] L81

Years: 1981

The L81 was the only Corvette engine for 1981. It produced 190 hp (142 kW) and 280 ft·lbf (380 N·m) from 8.2:1 compression, exactly the same as the 1980 L48, but added computer control spark advance, replacing the vacuum advance.

[edit] L83

Years: 1982, 1984

The 1982 L83 was again the only Corvette engine (and only available with an automatic transmission) producing 200 hp (150 kW) and 285 ft·lbf (386 N·m) from 9:1 compression. This was again the only engine on the new 1984 Vette, at 205 hp (153 kW) and 290 ft·lbf (393 N·m). The L83 added Cross-Fire fuel injection (twin throttle-body fuel injection).

[edit] L98

Years: 1985-1992

The new 1985 L98 added tuned-port fuel injection "TPI", which was good for 230 hp (172 kW) and 330 ft·lbf (447 N·m). It was standard on all 1985-1991 Corvettes (rated at 230-250hp and 330-350ft lb torque). Optional on 87-92 Chevrolet Camaro & Pontiac Firebird models (rated at 225-245hp and 330-345ft lb torque) 1987 versions had 10 hp (7.5 kW) and 15 ft·lbf (20 N·m) more thanks to 9.5:1 compression. Compression was up again in 1991 to 10:1 but output stayed the same.

[edit] LM1

The LM1 is the base 350 with a 4-barrel carburetor (usually with a Rochester Quadrajet) in passenger cars until 1988. Throughout its lifespan, it received either a points, electronic, and/or computer-controlled spark system, to conventional and feedback carburetors.

LM1s were superseded with the LO5 powerplant after 1988.

[edit] LO5

The LO5 was introduced in 1987 for use in Chevrolet/GMC trucks in both the GMT400 (introduced in April 1987 as 1988 models) and the R/V series (K5 Blazer, Suburban, and rounded-era pickups formerly classed as the C/K until 1986 which includes chassis cabs and 4-door crew cabs) LO5s were first used in passenger cars in 1989 with the Chevrolet Caprice 9C1 police package (the LO5 was not available on the standard (civilian) Caprice and Caprice Classic).

Although usage was for trucks, vans, and 9C1-optioned Caprices, the LO5 was also used with the following vehicles:

• 1992/1993 Buick Roadmaster sedan and station wagon
• 1991/1992 Cadillac Brougham
• 1993 Cadillac Fleetwood
• 1993 Chevrolet Caprice LTZ

LO5 usage was replaced by the GM LT1 after 1993 in GM B-Bodies until production ceased in 1996.

In mid 1996 the L05 was equipped with Vortec heads used in the 1996 G30.

[edit] L31

The L31 replaced the LO5 in 1996 - known as the Vortec 5700. Known as the GEN 1+, this was the final incarnation of the 1955-vintage small block, ending production in 2005 with the last vehicle being a Kodiak/Topkick HD truck. Mercury Marine still produces the L31 to this day. The "MARINE" intake is a common upgrade for L31 trucks.

het probleem met een Chevy 350 is dat ie af fabriek van alles tussen de 100 en de 400 PK kan hebben gehad, makkelijkste is DMV de casting nummers op de koppen en het ondeblok uitpluizen uit welk jaar en type auto hij komt en dan weet je meteen de specs van de motor, dit uiteraard als ze niet hebben lopen tunen met spul van bijvoorbeeld edelbrock e.d.
