I have a good running chevy v8 with 150k. it has no mechanical issues and is running smooth and reliably. im going to try and add a little power with headers, a complete exhaust, a better manifold, heads, and a cam. im also planning to have this dyno tuned which I have never done but am pretty interested in. my question is while I have the motor partially torn down for this (doing all work in the truck) is there anything I should do to "freshen the motor"? it will already be getting new gaskets when I reassemble but im not sure if everyone's definition of freshening a motor is the same. appreciate any knowledge you can pass my way.
