fiatboy Posted January 19, 2019 Posted January 19, 2019 The box of the '62 Bel Air (Don Nicholson's) seems to show the color of the Z-11 valve covers to be Chevy engine red. Is this correct? Thanks
W-409 Posted January 19, 2019 Posted January 19, 2019 Lots of Z11 information on this page: http://www.hanksz11page.com/z11info.htm . Can't find any information about the paint colors, but all of the pictures show the valve covers being silver. So that's what I would go with. Hope this helps.
Force Posted January 20, 2019 Posted January 20, 2019 (edited) Yes, most of the ones I have seen has been painted silver, some W engine high performance engines could also have chromed valve covers. As you may know the Z-11 was a stroked 409 to 427 cui, the Z-11 package was only available for a short time, the engine parts came late 1962 and the RPO code Z-11 Impalas was 1963 and 1963 was also the year for the Z-33 Mk II 427 "Mystery Motor" Edited January 20, 2019 by Force
Lizard Racing Posted January 21, 2019 Posted January 21, 2019 I have seen 409s with red, silver and chrome valve covers. Depending on the application, any of these would be correct. However, the 1963 Z-11 427 was a race-only engine. The valve covers were silver (brushed aluminum?) to match the hi-rise intake manifold. I hope this helps.
Nitrobarry Posted February 13, 2019 Posted February 13, 2019 Z-11 valve covers were different from regular 409 covers. Check out the top portion near the fuel filter. It comes to a sharp point in the corner. Then look at the bottom, it`s rounded. Easy to replicate. Also. the color of the covers has a "greenish" tint.
Ace-Garageguy Posted February 13, 2019 Posted February 13, 2019 (edited) The Z-11 valve covers are also slightly taller than the garden variety stamped steel 409 valve covers, to provide additional clearance for increased rocker travel with high-lift cams. Edited February 13, 2019 by Ace-Garageguy
afx Posted February 13, 2019 Posted February 13, 2019 (edited) Tamiya X-31 looks close, Titanium Gold. The valve covers on the 289 are painted that color. Edited February 13, 2019 by afx
