I bought a 427 SBC and couldn't be happier! My application is a little different because I put it in an airboat. After Skip heard me on the phone with Zach talking about an airboat, he jumped on the call and gave me solid advice about what to order. The motor is an absolute beast! I really want to thank Zach for his awesome customer service! He was very responsive to calls, texts, etc. and provided me with customer service that was amazing.
