Agree. The great majority of big and small block mopar heads are under-headed compared to what is available for a big or small block chevy.

I can run the math to show the different cam timing requirements for two different displacements at the same rpm with the same compression.

Just tell me how much compression and at what rpm you want peak torque and peak power and I’ll post up the cam timing numbers.
