Is this engine builder nuts?

well, his price is about average really. HP is about right too....

What you're seeing is the cost to build vs hp gained. I ran into this myself when trying to decide between building the 318 I had or going with the 440....I chose the 440. More bang for the exact same cost. A lot more bang.



And I guess it comes down to deciding if I need that much "bang." I think sticking with a budget 318 is the right choice. Now it just comes down to who's gonna build it
