Thanks! I really appreciate any insight like this into the 454, it’s my first one of those as well. I’m hoping this beast will last me at least until I have my 98 back running again.i have the same truck, its been great, at 214K miles it sheared off the teeth on the distributor drive gear and left me stranded, if you have the original distributor in there i would replace it
i put a Magnaflow full system on it, manifold back with new cats, all SS, it really needed it, if your truck doesnt like to be revved above 3K its time
