How many HP gain can i expect out of these heads when used in conjunction with basic bolt ons such as exhaust, 75mm TB, CAI, upper/lower intake, also what is the max HP handling capabilities of these heads? I plan on around 400-450hp when im finished with my motor. Thanks guys. LRS is the BEST!!!
Michael, the HP output from the Edelbrock heads on a Fox Body Mustang will vary but you can expect to see anywhere from 40-50hp increase over stock. Given the valve size you MUST check piston to valve clearance when installing especially with an aftermarket cam. These heads will support the 400-450 you plan to shoot for in your build.
