Tudo o que queria saber de motores de Corvette

a foto é de um magnífico motor ZL-1.

Cara amiga e amigo, vamos falar de motores?

Para começar a conversa, vamos mostrar todos os RPOs (código interno GM), aplicação, cilindrada e veículos de todos os Small e Big Blocks de 1955 à 1993.

Tenho certeza que isso será uma boa referência aos nossos leitores, amigos e proprietários do Corvette Brasil.


Todos os motores recebem estampado um código de indentificação que consite em um prefixo e sufixo.

A localização desse código depende do tipo do motor.

Se for um Small Block Chevy, então o código é estampado do lado do passageiro na parte da frente do cabeçote. Geralmente fica escondido pelo alternador ainda que muitos small block tem alternador do lado esquerdo à frente.

Se for Big Block Chevy então fica acima da cobertura da correia dentada.

O prefixo do código de indentificação diz onde o motor foi fabricado e quando o motor
foi fabricado.

Por exemplo, 0701 significa 1 de Julho. Note que o ano não é indicado.

Já no sufixo diz o ano, tipo de motor e transmissão como foi originalmente na linha de montagem.

As Seguintes abreviações.
AB = Freios à vácuo.
AR = Reator de injeção à ar.
CA = California (isso é um tremendo castigo!)
HD = Motor para aplicações Heavy Duty ou competição.
HDC = embreagem heavy duty.
HP = High performance.
LP = Gas liquido propano.
PG = Powerglide.
MT = Câmbio manual.
MT-3 = C6ambio manual de 3 marchas.
SHP = Alta performance especial.
TH = Turbo Hydramatic.
T(x) = ignição com transistor. Onde x = 1 para quadrijet.

Um exemplo de código de motor seria:

V0107CLJ, ou seja:
V = fábrica
01 = Janeiro
07 = sétimo dia.
CLJ = tipo do motor, veja lista abaixo.
