I have a set on a 462. I’m very happy and bought them in 2012. 56cc chamber with 350cfm option which they no longer offer. The short block was bought used with a few passes and had heavily modified WP’s that the previous owner was keeping for this aftermarket block build. The HP’s made the same power and torque at less rpm. I think for the money they are a great option with plenty of room to grow.
