Boss 429 engine page.
Here are two veiws of the Ford Boss 429 Engine.
Boss 429 without air cleaner to expose the original Holley 735 cfm carby. Note the special body bracing bar that was fitted between the shock towers to stop chassis flexing.
Another view with the air cleaner fitted. Note how wide the cylinder heads are compared to a normal V8.
Here is a photo of the ultimate Boss, the rare Can Am 494, an exotic version of the Boss 429 NASCAR engine. Using standard Hilborn injection only thirteen (13) full aluminium engines were made and five (5) of the ultra rare magnesium engines. A reputed 700HP + was obtainable from this setup.
