FULL DYNO RESULTS on this POWER ADDER BBC Stroker. Using a cheap Gen-V 454 core from the junkyard, we built a Multi-Purpose 496 stroker. Using the right combination of parts, we were able to make BIG power then run Power Adders for even more HP! Here in Part 1, we ran the motor NA then with a healthy dose of Nitrous. Part 2 will cover a 6-71 blower and Procharger Centrifugal Supercharger.
