quench vs no quench?

Man, I think there's a lot of independent variables that are being ignored or minimized for this conversation.

HP is more valuable than torque for racing. That high torque engine will be useful for a truck. Hence diesels over gassers.

There are all sorts of limitations that affect your ability to build HP and make it useful, mostly centering around budget. Dedicated heads up race car engines really should not be considered in the same frame as street or bracket engines. S/F....Ken M
