GR-40/GR-350 Suspension Systems | Individual GR-40 Upgrades | Complete Parts List

Engine mods need to be tailored towards the customer's individual goals, but for street performance at reasonable cost, the Ford motorsport GT-40 Aluminum head and GT-40 intake manifold are hard to beat.

When coupled with the appropriate exhaust and induction system components, the 302 can easily produce 325 reliable horsepower on pump-gas and shed 40 pounds more of front end weight. These induction changes may not offer the same massive torque-hit of a blower installation, but produce a power curve that is much more flexible.

Complete cylinder head and induction system kits are available from Griggs Racing starting around $2,500. We also offer complete turn-key stroker-motors based on the Fontana Aluminum block.
