Going a step past just throwing yet another opinion out there............

Wouldn't the determining factors of using the LY's be the mass of the piston, rpm's applied and the dutycycle/history of the rods themselves???

A .590 cam and Victor heads do seem to be a bit much with forged KB pistons. Lotsa bobweight slingin' around.

I would think either less cam, read rpm's, or better rods & pistons would be the way to go. Or leave it dialed on "Kahboom".

I'm frugal, but not that cheap.
