This is a mild stroker setup for the 390FE engine, using a 3.980" stroke to achieve a displacement of 416 cubic inches. These kits are a balance between top and bottom end power, making them ideal for many applications. Various levels of compression make these kits great for all types of setups - naturally aspirated or with power adders. Bore sizes are set 4.080".
This is a bit more wild of a stroker setup for the 390FE engine, using a 4.125" stroke to produce even more displacement than the 416. This configuration will be a bit more bottom-end heavy than the others, with less emphasis on top-end power. Great for applications where high RPM aren't as important, such as street/strip use. Bore sizes set at 4.080", with compression ratios from medium to high.
This is the largest stroker combination available for the 390FE, using a 4.250" stroke to achieve 445 cubic inches of displacement. Due to the long stroke this combo makes monster torque, although at the expense of top-end RPM. Regardless it is still a great setup for street applications where the RPM are usually fairly low to begin with. Applications are in the mid to high compression range, making them great when run naturally aspirated. Bore sizes set at 4.080".
This is a stock style setup for the 428FE engine, featuring a 3.980" stroke and bore sizes ranging from 4.130" to 4.190". Whether the kit is intended for stock replacement or racing, various levels of compression will allow for improved performance with emphasis on top-end power and high RPM.
This is a mild stroker setup for the 428FE engine, using a 4.125" stroke to achieve a displacement of 442 cubic inches. These kits are a balance between top and bottom end power, making them ideal for many applications. Various levels of compression make these kits great for all types of setups - naturally aspirated or with power adders. Bore sizes are set 4.080".
This is the largest stroker combination available for the 428FE, using a 4.250" stroke to achieve 455 cubic inches of displacement. This configuration will be a bit more bottom-end heavy than the others, with less emphasis on top-end power. Great for applications where high RPM aren't as important, such as street/strip running either naturally aspirated or boosted. Bore sizes range between 4.130" and 4.160".
