This is a stock style setup, featuring a 3.750" stroke and bore sizes ranging from 4.350" to 4.380". 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, featuring a 4.150" stroke and bore sizes ranging from 4.350" to 4.380". This kit is a good balance between top and bottom end power, making it ideal for many applications. Various levels of compression make these kits great for all types of setups - naturally aspirated, or with power adders.
This is a bit more wild of a stroker setup, using a 4.250" stroke to produce even more displacement that the 493. 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 quite as important, such as street/strip running either naturally aspirated or boosted. Bore sizes range from 4.350" to 4.380".
This is the most radical Chrysler Big Block stroker setup, using a long 4.500" stroke to produce a huge 535 cubic inch 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 aren't extremely high to begin with. Applications are in the medium compression range, making them best when ran naturally aspirated. Bore sizes range between 4.350" to 4.380".
