Well there are many factors that come to play in rebuilding a motor. It's not just taking out old parts and replacing with new. There is machining involved to do it right. I HIGHLY suggest learning about this. Take the time to study on engines. I have and still learning new stuff after 12 years. Takes time and effort. Engines are really easy to understand(most of the time) and google with animated videos will be your best friend. Learn all the parts in a motor and what purpose they serve and how they work. Then look at how to vidoes on rebuilding engines. Engines are air pumps put together Precisely and Timed. Small things are critical. The 292 will be a super easy engine to learn off of. I would also recommend getting a 1965 GMC Shop manual. It will give you specs and pictures.
