3.23 gears

Talk about a mismatch.

You're building a high rpm engine and dog it out with those gears.

Years ago I built a .060 over 413 with the street hemi grind cam, much milder than either of your choices, same heads but not as much compression. It ran ok with 3.23's and a stick but it kicked butt when I put 4.10's in.

You need more gear and better heads if you really want to run a .557 cam.
