Im not super familiar with flat plan crank engines, but I didn’t think they churned out much torque when compared to a similar cross plane crank motor?
and someone repowering a “classic” is going to spend $33k on a 400hp motor that sounds cool, but looks like crap? What are they smoking up there?
I’m confused…

Just found this in addition to;
”Typical required modifications include new engine mounts, adjustments to exhaust components and regearing the sterndrive unit to compensate for the 409 MPI engine's higher rpm range.”
