A 350 Chevy. The last time I needed a used one they were getting hard to find anymore. I am a old retired Chevrolet mechanic and now have a small repair shop. Now getting to your Briggs your car engine tools like hones and ring compressors might be a little large. If you are rebuilding engines you should know what it cost if you have to have machine work done, not cheap. You should be able to buy a lot of your Briggs parts from NAPA. If it was me other then throwing a lot of new parts into a old block without any machine work I would get a used engine . You should be able to pick up a good used engine from a mower salvage for around 100 dollars.
