We will see how strong these motors are. I have funds set aside for a build if I needed.
Remember these heads do not make the same torque as 11-14. Torque is down 80-90 over my 13 TVS. This will help some with living at this level.
It has a boss crank and rods which have held 850 in lots of motors.
The weak point is the piston. It is coated and a little stronger than 11-14 pistons. Running E85 also helps with detonation. The timing is fairly conservative as well.
Guess we will see......
