Build a mock Boss 351 engine with a standard 351 block and Edelbrock Performer RPM Cleveland heads using this Performer RPM E-Boss 351 manifold. For both high performance street and competition, the dual-plane design makes outstanding power from 1500 to 6500 rpm and the Cleveland port layout and intake bolt hole pattern fit both 2V and 4V heads. It features 9.5" deck height, Windsor end rails, water neck and distributor hole clearance, front and rear water bosses with a standard square bore carburetor pad. Edelbrock carbs will work with Ford automatic overdrive trans (AOD) when used with Lokar bracket p/n 625-SRK-4000.
