1966 Corvette

1966 Corvette Roadster 327 / 350 HP

This car was manufactured in very late June, 1966. All of the major components support this, except for the cylinder heads, which are a little earlier, from February. All of this decoding was done using Colvin's book " Chevrolet by the numbers, 1965-69" You are encouraged to have your favorite Corvette expert review this information. We're not Corvette experts, so you should make sure these numbers match to your satisfaction BEFORE purchasing the car.

Correct Holley, P/N 3884505

Engine Casting date F 9 6 means June 9th, 1966. The Car itself was built in 4th week of June, 1966, so this matches right up .

Correct 3858174 Block

HT 124819 - Stamping matches the VIN #. HT means 350 HP, 4 speed, Hi lift cam. Reference page 42, Colvin's "Chevrolet by the numbers, 1965-69". I've had 2 Corvette experts look at the stamping, and they both think the block has been decked and restamped, using the correct and very likely the original block.

Here's the vin tag.

Here's the trim tag. SDT trim means black interior. 988 Paint means Milano Maroon, the color we see on the car today.
