That makes sense testing the 427 in the 289 body.

Another question: was the oval air cleaner used in any model?

I noticed the 289 had either a 14" chrome or webers and the 427 depending on street or competition had the single or double carb setup with the turkeypan or just the Stelling and Helling 8" chrome air cleaner setup.

Thanks, Randy
