First engine hit the dyno today. James at Bostick Racing/Marine Engines in Yuma is doing an amazing job. The goal was to build matching 5.7's with forged pistons, hydraulic roller cams, roller tip rockers, balanced, etc. I wanted higher quality internals than the ones I saw being sold online as marine crate engines, James understood and went to work. Very happy with the outcome. Here's engine 1 dyno videos ... on to engine 2!
