With a max overall height of only 10.44\", the Mid-Rise manifold is an excellent choice for street and performance street\/strip applications with a powerband from 1,500-6,500 RPM and limited hood clearance.  It's perfect for turbocharged, or normally aspirated  applications.\n\nThis manifold is modular, and the plenum adapter (PN 300-267) will accept all of the popular Holley LS Hi-Ram plenum tops as a foundation for custom induction systems.\n\n*** The front and rear height measurements listed in the Specs section are referencing the overall height with the top plate installed.
