Hooker Turbo Manifolds 5.3 Fitment issues
 

Just FYI, if your thinking about using the Hooker Turbo Manifolds with your 5.3 swapped 67-72 the manifolds won’t clear the original style engine mounts. You will have to switch to the later style clamshell mounts. Yes this means changing the engine perches too. I used OEM perches I found in the Junkyard. They now clear the mount, barely. Holley knows about this and this was their recommendation.
