Are you trying to make some NA power? This is the combination you need. We made 1000HP + with our LME canted valve heads paired with this 468" Tall Deck Shortblock! This Combo has been proven in drag and drive, road racers, and drift cars. Not only does it make some big HP, but it's reliable and proven! It should be noted a road race/engine application will have a little less peak power to ensure a little more power downlow for cornering. Drag Racing combos will be closer to the 1100 HP mark.
