Ok, fires up but will not stay running.
Here's the summary of what happened. A buddy's 69 Mach 1 (351 Cleveland) overheated and engine shut down. We replaced water pump and radiator. Car would not fire up. Replaced MSD box, fires up but will not stay running (it will not maintain an idle). Adjusted timing but will not dial in to keep engine running. Gonna pull the timing cover to check timing chain and sprockets. Feel free to chime in and give any thoughts
Thanks again guys
