Clifford 4.0 4.2 Jeep AMC Holley 650cfm Blow-through System
This setup is from our first magazine cover build. It has been sitting this entire time(6 years), includes: Fully ported and polished Clifford 4.0 or 4.2 intake manifold with the four hole adapter(Intake pattern has been corrected), 650 Holley XP "Blow-through" with pressure tubes, Aeromotive regulator 1:1 for carb, #8 AN plumbing, extremely hard to find low rise carb hat that works, MSD Pro-billet distributor with wires. All of these items have only the original dyno time. On a mild cammed stroker this setup on 17psi made well over 650HP/700TQ with no fueling issues and great driveability.
