Oh man that is a sweet truck, and reading this thread a got some good info on the 292, I have one thats in my 66 truck and you guys answer some good question for me. I didn't think about the oil but remembered something having to do with detergent oil or non detergent oil and not having leaded gas anymore i am sure some here has the answer, is 10/40 going to be the best for my 292 ? not trying to jack the thread..... that is a killer truck
