I’m currently measuring out my rotating assembly from 440 source. So far my rod bearing clearances appear to be 0.0024-0.0028, measured with a ten thousandths rated micrometer and dial bore gauge. I know the rule of thumb is 0.001 per inch of journal, which for my 2.2” rod journal should be 0.0022 for a minimum clearance. I understand people usually go a bit higher on performance or boosted/high rpm stuff.
What is the max clearance for a street strip build? Is the 2-6 thousandths extra clearance just right or too much? I’m assuming it’s good to run, and a bit of extra is better than too little. But it’s my first build, so I figure I’d run it by some people more experienced than myself.
