Now, who built this 103?

There are a LOT of details in your build that make or break if you get 94 hp or 103hp. The Andrews 54 cam is a "mild" cam with a 42* IVC and 0.555" lift. Do you actually know through measurement that you are getting the compression you think? Did the cam get degreed in or checked? I notice there was zero intake/t.b. work done. What are the particulars on the SBC heads? What is the volume of the combustion chamber? What was the deck height measurement?

The true duals are not helping your cause either, especially on the bottom end torque build which helps set the stage for the top end charge.

And as others have mentioned, I would doubt that the tune is complete.

Don't take any of this the wrong way please, just trying to help you get to the bottom of the issue so you can know the truth.

all the best!

That is what I am dying to know, who did this 103 build?
