trw slugs from 20 yr ago??
I'm going to guess your piston is .030 below deck?. and went with a shorter taller cam.... These things do not add up to greatness. Should be able to get some great torque, while your heads support 460 other things might not be as supportive.
380/450
with .065-.070 quench ...you will certainly be paying attention to detonation issues or really close eye on your total advance.
