WHAT YEAR ENGINE?

HEADS

(3.740 & 3.800 = top outside diameter of cylinder)

These sketches of the combustion chambers will help you determine which engine you have. All compression was controlled by the cylin-

der head not piston design (exc. for domed pistons in some smog engines). Pay special attention to the area around the spark plug hole.

The 140 can easily be determined by the 2 carburetor mounts per head and larger valves. The turbo heads often look like other heads but they have several

differences (no provision for carb. choke thermostats, right head has drain tube into valve area, both heads are tapped fine threads and approximately 1/2”

deep for the head heat sender). See also head number chart.

Reprinted with permission from the San Diego Corvair Club. Furnished by Jerry Becker.

Before ordering head gaskets, rings, etc., you may want to double check these sizes – as engines do get switched!

HEAD NUMBERS

We have found that the engine codes by the oil filter are often inaccurate and do NOT take into

consideration that heads may have been changed. We suggest you go by the head numbers. This

should be a 7 digit number within an inch of the valve cover gasket area. This list is NOT complete! See picture bottom of next page.

These numbers are found on the top of the block near the gen./alternator plate (near oil

pressure sender). These are some of the common numbers. Please note that GM was not

always consistent in their use of these numbers and many times heads have been changed and basically changed the type of engine. Chevy did NOT always

refer to the horsepower rating of an engine so in various references in the shop manuals, etc., you may find the following: if they make no mention, the engine is

the low horsepower for that year (80, 84, 95). High performance was the next option engine (98, 102, 110). Special high performance always was 140, or Turbo,

(either 150 or 180). The most complete and accurate listings are in the “Junkyard Primer” and “CORSA Technical Guide”. XXX = replacement case
