Empezado por gringoc

Tengo unas fotitos de los avances para compartir....mañana mando el volante Rocky al tornero para adaptar acople....

gringo averigua si tu motor es balanceado internamene antes de hacer la pega, en el .4.3 va balanceado en el volante y adaptar un volante lo deja desbalanceado

Chuta ahí me dejaste pillo con el cigueñal !!!!!.....las precauciones que tomé fueron dirijidas a los diferentes pesos(Klg).....tomamos el convertidor de torque y lo pesamos.. lo mismo hicimos con el volante y kit de embrague y ambos estaban parejo ,poca diferencia....

Los V6 Chevy con balanceados externos, es decir con el volante.. puedes poner el original del motor, o mandar a balancear el congunto, sino va a durar menos que un candy.......

chevota tenia para el 4.3, no se si sera el mismo que para el 3.8

Me preocupa el tema del balanceo vamos a tomar muy encuenta sus advertencias ,el volante en este momento se perforó al centro a medida del motor V6 todavía no se asen las perforaciones de los pernos...lo retiré antes para verificar si la perforación del centro había quedado perfecta y tambien para aprovechar instalar el arranque con respecto a la cercha...todo eso está listo...


Como dato el kit de embrague del V6 es mas grande que la campana del Rocky(no entra) por eso opte por embrague Rocky...

Mañana estonces me preocupo del balanceo del volante... y de las otras pegas tambien jijijijijj

Se me olvidaba que tenía unas fotos del avance recargado (de problemas)

El motor originalmente tenia caja automatica no?, el volante de la primera foto es el original?

tienes fotos por el otro lado?

Chevrolet 90-Degree V6 engine

The Chevrolet 90° V6 family of engines began in 1978 with the Chevrolet 200 cid (3.3 L) V6 as the base engine for the all new 1978 Chevrolet Malibu. This engine family is still produced today, as the 4.3 L V6 engine used in Chevrolet and GMC trucks and vans.

These engines have a 90° vee block with 12 valves activated by a pushrod valvetrain. All engines have cast iron blocks and cylinder heads. The engines are based on the Chevrolet Small-Block engine, and the V6 is formed by the removal of the #3 and #6 cylinders. The V6s share the same 4.4" bore spacing and 9.025" deck height as the V8 engines. Many parts are interchangeable between the 90° V6 and the small block V8 including valvetrain components, bearings, piston assemblies, lubrication and cooling system components, and external accessories.[1] The 90-degree V6 engine uses the same transmission bellhousing pattern as the Chevrolet small-block V8 engine. The oil pan dipstick is located on the passenger side above the oil pan rail; this design was phased in on both the V6-90 and Small Block Chevrolet assembly lines sharing the same casting dies. All the engines use a 1-6-5-4-3-2 firing order.[2] The engines in this family are longitudinal engines, and have only been used in rear-wheel drive cars and trucks.

3.8L (229 CID)The 229 cid engine was first introduced for the 1980 model year and was produced until 1984. This engine replaced the 250 cid in fullsize Chevrolets and Camaros as the new base V6. Additionally, the intermediate Chevrolet Malibu and Monte Carlo also used the 229 cid as a replacement for both the 200 cid V6, and the 231 cid Buick V6. Both the 231 cid Buick V6 and the 229 cid Chevrolet V6 are 90 degree V6 engines, and both are often referred to as the 3.8L V6. These engines should not be confused as being the same, and are completely unique engine designs.

The 229 cid has a 3.736" bore and a 3.48" stroke, identical to the Chevrolet 305 cid V8 engine. The 229 cid used the same 2.45" main bearing and 2.10" rod bearing diameters as the 200 cid V6 engine. Also like the 200 cid V6, the 229 cid used the same crankshaft with the 18 degree offset throws and the same 5.7" connecting rods with 0.050" narrowed ends. It came equipped with 1.84" intake valves and 1.50" exhaust valves. The 229 cid V6 was only equipped with a 2-barrel carburetor. For 1980 the 229 cid used a mechanical Dualjet. From 1981 - 1984 the electronic Dualjet was used along with the GM's CCC (Computer Command Control) system. The 229 cid was rated between 110 and 115 hp (86 kW).

Year Horsepower Torque Bore and Stroke Carburetor Compression Ratio
1980 115 hp (86 kW) @ 4000 rpm 175 lb·ft (237 N·m) @ 2000 RPM 3.736" x 3.48" 2-BBL M2ME 8.60:1
1981–1982 110 hp (82 kW) @ 4200 rpm 170 lb·ft (230 N·m) @ 2000 RPM 3.736" x 3.48" 2-BBL E2ME 8.60:1
1983–1984 110 hp (82 kW) @ 4000 rpm 190 lb·ft (258 N·m) @ 1600 RPM 3.736" x 3.48" 2-BBL E2ME 8.60:1

Chevrolet Small Block V6 Engine

The Chevrolet Small Block V6
The Chevrolet V6 has become a very important Jeep conversions engine, and is swapped into many Jeeps with great frequency now.

By 1978, Chevrolet had 23 years of building its famous Small Block V8 under its belt. The energy and fuel crunch of the era dictated a lighter, leaner motor than the V8 and GM took on the engineering and production of an important new engine.

Development
This new V6 would essentially be a V8 with two cylinders truncated, as Buick had successfully done with its V6 in the 1960's. The Chevy 90-degree V6 had the same rear block face & bolt pattern, as well as the same style of engine mounting bosses and accessory packages as its bigger brother. Because its crank was a shortened version of the V8 crank, this motor was an "odd-fire" design, firing its cylinders at uneven intervals. The motor was internally balanced and would feature the standard two valves per cylinder.

The Release and Evolution The motor first featured a displacement of 200 cubic inches and in 1980, this was increased to 229 c.i.d. It was largely found in Chevrolet cars during this era. In 1985, the V6 underwent its next upgrade to 262 c.i.d. - equivalent to 4.3L. It was converted into an even-fire motor. To do so, it was necessary to balance the motor externally and the flywheel was no longer interchangeable with the earlier V6's and most SBC V8's. In 1986 it received the one-piece rear main seal improvement that was also seen implemented in the V8's. The V6 was the first to be called the "Vortec" engine - nomenclature that GM would eventually pin on all of its advanced truck engines to this day.

Si..... el motor viene con caja automática....la primera foto es del volante donde aperna el convertidor de torque......


Gracias por la página gringa....todavía no encuentro números que me indique la cilindrada del motor o Hp........el que está bien clarito es este GM14020533..
