Vortec Build Combustion Chamber
|
A key characteristic of the Enginequest heads is the compact Vortec-style combustion chamber. The deep spark plug position helps hasten the combustion process, and the 62cc as-cast combustion chamber volume is a vital factor in helping us achieve a workably high compression ratio with our dished pistons. We had the heads milled to achieve a final volume of 58 cc, which provided a performance-inducing 10:1 compression ratio in our assembled engine. View Related Article
