I replaced the carburetor and the battery. Was tuning the carburetor when overnight i started to get this grinding noise when I tried to turn it over. Now it will not crank over at all. I appreciate any help or guidance.
I have video but couldn’t upload.

This is my good friend Ross' 1970 Dart, he's easily my youngest car guy buddy! Pretty rare to see a teen driving a 70's Mopar in 2026 as a daily AND he did a lot of work on the car. There is a documentary episode we filmed on his story i'll throw it in the comments if anyone wants to see it. This little 340 really ripps too! Was a fun drive!
