Whipple-supercharged airboat engine in the shop for a freshen-up. While it was apart, we upgraded it to one of our new engine blocks that we’ve been testing extensively over the past several months.
The results are in, and the data speaks for itself. These new blocks have proven to be a significant improvement over the RHS blocks we previously used, offering better strength, durability, and reliability. We’re excited to get them out there and keep delivering the best possible products to our customers.
