Hey guys, can’t seem to find this number anywhere. Anyone know how many of these CST 10’s were produced with the big block?


Thanks in advance!

It ought to be interesting to see if anyone can find those numbers. Based on what I know the 402 was simply a 396 with a .030" overbore. In some years they were called 402's and others they were Turbo 400's.

To make it even more confusing there were 402's put into cars but labeled as 396's.

It is my understanding that a "Turbo 400" was the name used for a hydramatic transmission:

The 402 was continued to be called a 396 engine. One reason probably was the Chevelle SS 396 . That engine was called "Turbo-jet 400" (and 454) not to be confused with the small block 400.

The GM 3 speed with torque converter automatic automatic transmissions that came out in 1964 Were Turbo-hydramatics. First was the T.H 400, Then lighter duty 350 and 250 series.

My error. Thanks to Gene for the correct info. I agree that in some vehicles the 402 was called the Turbo-Jet 400.

And yes, that can be confusing with the similar transmission designations.
