Overated BOSS Mustangs?

Hah, from what I understand the cleveland style heads did not possess a hemi or even a semi-hemi combustion chamber. The correct description would a poly angle combustion chamber desgined to take advantage of the canted valve placement. the BOSS moniker was a marketing gimmick thought up by Semon "Bunkie" Knudson and Larry Shinoda.

there where 3 BOSS motors, A BOSS 302 (69-70), BOSS 429 (also 69-70), and the BOSS 351 (71-? this engine in its preliminary trim was basically a 351 4V cleveland with upgraded internals and a solid lifter cam).

The BOSS 302 cars where built to homolagate a car for trans-am, They featured heavy duty components as well as modified chassis.

The BOSS 429 was basically a Mach 1 that was converted by Kar Kraft to fit the big ol' BOSS 429 engine. Shock Towers where moved out a coupla inches and there where probably a few more mods done as well.

The BOSS 351 was porbably the least factory modified of the 3 cars, since it seemed to just be a collection of HD offerings combined with a solid lifter 351 cleveland.
