The solid I'm considering is the Comp XS274S. Plugging it into the CamQuest program, it showed about 10 more HP @ 500 RPM less, and nearly 40 lb/ft of torque advantage over the XE285HL. Its description says it also requires less compression and converter than the 285, which leads me to believe it would be more streetable. Lets see..... more power, lower in the band, and better streetablility???? Is there anything here that doesn't sound good?
