Yes, it will have the Winters 'snowflake' on the #1 intake runner. Intake casting number will be either 3972110 or 3972116. -Al

Did these cars have finned valve covers? This one has them but I haven't seen a picture from the top.

Yes...finned aluminum valve covers. Pay particular attention to the front face of the cylinder heads.

From the pictures the heads look like camel humps.

The early double hump heads do not have accessory holes or those flat areas. After 1969 they do. Don’t know the correct casting number but it’s pretty easy to get that info and check the heads. Intake definately should be the hi rise GM aluminum. Jerry McNeish is the man to talk to about the authenticity of that car.

Correct casting numbers for the heads will probably be 186 or 041. Possibly 414, as there are some claims they were used in production, though historical evidence says they were produced a few years later as replacement castings.

I knew a guy who bought one new back in the day and it was a way cool light green with black stripes and stupid fast. I love those cars.
