I think "351 Windsor", "351 Cleveland", and "351 Shelby Equipped" side emblems are available. I get most of my OEM British parts from europaspares.com (cobraspares.com - same company).

Tony Branda and Finishline are other sources.

That being said, Cobras were made in '63 & '64 with 289 HiPo motors. The side emblems said, "Powered by Ford". In '65 & '66, they came with 427's and 428's. The side emblems said, "427 Ford Cobra".

Today, "427 Ford Cobra" generally denotes an FE series engine; 390, 427, 428. And "Powered by Ford", means any other Ford engine, even the 351's which didn't come about until the car was out of production (351 Windsor in '68, 351 Cleveland and 429 fat block in '69).

No emblem at all usually means Powered by Chevy. Ha Ha.

Also, today, the waters are muddier still with stroker kits so readily available. 347's from 302's, 393's and 408's from 351's, 521's from 460's. (add a supercharger and get 1,000 RWHP).

Anyway, I stuck a "Powered by Ford" emblem on mine. The valve covers say "Ford Motorsport". The actual displacement (357) is nobody's business but mine, and is subject to change anyway (393). Some guys will ask you, "So what do you have in it?", since you don't have the displacement advertized on the side of the car. It's a great conversation starter.
