This Edelbrock #61729 Victor Series cylinder head is for use on 1967-1991 318-360 c.i.d. Chrysler LA engines. It features fully CNC ported 58cc combustion chambers and has an intake port volume of 225cc. This cylinder head is an in-line valve design incorporating a 16 degree valve angle (stock is 18 degree) for improved air flow and increased power levels over heavily ported stock versions. This head also features the Chrysler W5 bolt pattern and has raised exhaust ports. The intake port has also been raised approximately 3/4" and the flange has also been extended to accommodate a stock (race) intake manifold such as Edelbrock's Super Victor #2815. Finally, a 5.56" overall length valve (+0.600" from stock) and raised rocker cover permit larger port cross-sections than in the stock head. Four versions are available; bare, bare with valves, complete (for hydraulic/flat tappet cams and solid roller cams) and Pro Port Raw. End-seal spacers are provided.
