1970 f100 with 6.4- 390 bored 30 over with rv cam. Im not quite sure what the bolt is for, it is under the entire distributor, not the clamp that holds it down but when distributor is completely removed I looked down through intake into block and there is a 6 sided bolt directly under distributor. I removed distributor and reinstalled it next day and put a used carberater on it and the motor started and ran with a slight miss to it so I started to turn distributor and engine started idleing up and I thought it was a vaccum leak or idle just needed turned down but I pushed throttle down and carb shot big flame out of it so I assumed I needed a new carb. Installed. Another carb (not new) and engine sounded like it had no fire. I then took #1 spark plug out and brought to tdc on compression stroke to see if it was in time and it seemed to be. Left spark plug out and turned motor over trying to start and engine almost started but not all the way. Put #1 plug back in and motor sounded like there was no fire again and would not start?
