The notch isn't that much, nor is it difficult. And that is the only mod required to stuff a 4" crank in one. 12.5 to one is easy too with 4" crank. A zero deck flat top will get you there.
Sorry! Misread. Thought I read 12.5 compression, not 12.5 et.
Honestly for a 12.5 car, a cast crank with I beam rods, and hyper pistons would be fine. You will need a dish piston for 9.5 compression. Might as well run a 4" crank, as it doesn't really cost much more to up the cubes. I think you could build this motor as mild as you want and run mid 12s.
If it were me I would run a cam in the mid 280 duration range, an rpm intake, or single plane, and a holley 750 carburetor.
Just so you know it may run better than mid 12s when done.
