Thanks. That's what I found out too: I believe the engine comes from a 1974 Police's Camaro.

Christian

There were no police Camaros in 1974. Pursuit package Camaros were introduced for police use in 1992 or 1993 and were produced through the 2002 model year.

So, what do you think "  t4OO police " stands for in MrMako's answer ?

Christian

The 1974 indication is not for Camaros but a 350 for full size police apps according to the information from Mr.Mako. In 1980, you could get the 305 in a full size or Camaro.

My guess on the T400 is that the police application came with a Turbo Hyrdromatic 400 trans.

My 2 cents.

Luke

The t400 means a turbohydromatic automatic transmission mated to a 350c.i.  engine for a fullsize sedan application, possibly a Caprice. GM had very a very small protion of the police market in 1974. Chysler had the majority of the police interceptor market.

According to my well worn Copy of the "Green Book"  ..
(the complete Chevy V8 Engine Code book  from 1955 thru 1985)

The CMJ code was used in 1974 for passanger cars ... rated at 160 Hp
     all automatics, all 4 barrels...and also used in Police Cars

The same code was used in 1975 and 1976 models rated at 145 Hp
with 2 barrels and dropped into Passenger Cars, Monte Carlos and Chevelles

The code also was used in 1980 (305's) rated at 155 Hp ...also
listed as a passenger car engine,...

Only codes used in 1974 Corvettes were
    ckz  cla clb clc cld clh clr cls cwm cwr cws or cwt

If your engine runs strong ..do you really care... ?   lol
