CADILLAC
Bulldog Performance
The first cylinder head developed by Bulldog was the Cadillac application, and according to Bulldog, that process revealed that the Cad has tremendous potential. The Bulldog heads go a long way toward releasing that potential, as the big-inch Cadillacs can now breathe deeply. Flow bench testing shows over 300 cfm on the intake side out-of-the-box, with plenty of room left for porting. The intake openings are CNC'd on the Cadillac heads, while the exhausts are not (we're told they needed no extra help). Bulldog also offers a single-plane intake for the Cadillac V-8 to support the heads, though stock-type intakes can be used. Edelbrock also offers a Performer dual-plane for the Cadillac V-8.
