9 Fin Corvette valve covers

[m22mike]

Anyone know the history of the cast aluminum 9 fin valve covers ? Like when and how long were they used ? Were they specific to Fuelies or Dual quad cars ?
What are they worth ?

Thanks Mike

As I remember the Fin count was changed in the Early 60's.....I don't think there was any specific's to Intake configuration, just early and late covers

The 9 fin covers were only used in 56 and early 57. Look on NCRS and I'll bet they have more exact information. They aren't real valuable, about $2-300.00, maybe a little more.

9 fin covers are for all '56's and '57's through serial # 4000 and something - don't remember exactly - like Apr/May cars.
Late '57 -'58's had 7 fin covers
If the 9 fin covers are not notched on top - early '56
Good covers are worth at least $400
If they are early '56 let me know if you are looking to sell

After a little search I came up with this.....


<font color="blue">Nine fin valve covers are correct for all 1956 225 H.P. and 270 H.P. engines. They are also correct for 1957 cars through serial number E57S4500. (A mix of seven and nine fin low script valve covers was used between E57S2000 and E57S4500.)</font>

One of the Corvette vendors has a pair listed for $475.00. As you know prices vary. Sorta like a BE rear end is worth more here than anywhere else.

Yo Dog427/435, pm me or call me at (585) 748-8777.

Somehow over the years I have aquired 3 (yeah, go figure, 3) of these valve covers. I haven't looked at them in sometime but I know they are the early ones. I was going to figure out how to make a "spacer" for them so I could use them on later motors, but if you have a need for them, please contact me and lets see if they are correct for your application. Out with the old, in with the other old stuff.
