Help me build my 340!

A well ported set of Edelbrock heads wi provide what you'll need in terms of air flow. The "W" series head is not needed. GoldDuster318 uses IIRC, EQ heads to get to his 470hp level. You could also do the same and ethier use more cam and-or a single plane intake.

The stroker idea is IMO and excellent idea for the amount of torque it will add. This extra stroke wod make it very streetable.
