A little V12 vintage Ferrari work finished up today!

LT1 & LT2 factory intake manifolds ported and ready to ship! These are the perfect add on to any bolt on cold air kit, ported throttle body, heads/ cam set ups. They add good horsepower and torque across the rpm range as well as added wide open throttle sound!

Clean, bagged, and ready to ship $375 with your stock LT1 intake manifold core in exchange. $600 with no core exchange.
