    Optimal Ignition Timing??

    Attached are two videos of the findings after removing the intermediate shaft and bushing. Both the bronze bushing and slot in intermediate shaft gear had some wear on them. I have not checked to see if this solved the timing mark jumping around. However when driving today on the highway it...

    Optimal Ignition Timing??

    Thanks for all the feedback everyone, really appreciate each and everyone of you. I went home during lunch and checked the engine vacuum and also tried to show the timing mark jumping around (not very successful). It looks like it jumps about 5 degrees to the before side then jumps back to...

    Optimal Ignition Timing??

    I checked that and the distributor was held down tight and I could not move it myself.

    Optimal Ignition Timing??

    Engine temp when I am setting it is at about 165-170. I do disconnect the vacuum line and plug it at the carb and line. RPM's at at about 650-700. I don't think i have any vacuum leaks, when I plug in my vacuum gauge it is at a steady 17-18" of vacuum. I do have an electric choke on the...

    Optimal Ignition Timing??

    New findings in this matter. In the process of trying to determine total timing this weekend, I noticed that the initial timing went back to 12 BTDC after I had set it to 18 last week. When pointing the timing gun at it the ignition timing mark also jumps around about 1/4” side to side. The...

    Optimal Ignition Timing??

    I have not done that but plan on doing it this weekend. To what RPM's do bring it up to read total mechanical timing?

    Optimal Ignition Timing??

    Will do thank you. I did change the springs in the distributor to recurve.

    Optimal Ignition Timing??

    I agree pnora. I do have a fuel return line back to tank that I added to avoid vapor lock. We had a brutal summer in Texas this year and that helped a lot. When hot it starts back up right away with just the key. If it sits for several hours I pump the pedal twice, wait about 10 second for the...

    Optimal Ignition Timing??

    Car is a 1967 Coronet 440 with 318, automatic 727 Torqueflite. I have been having a lot of fun with it after chasing a rear main seal leak and bad distributor gasket/clamp. I have upgraded the engine with hooker headers, flow master dual exhaust, Edelbrock intake and four barrel carb. The...

    Please help! Bad timing

    They do look unaligned, but as I turned the engine they did align in the 6 to 12 locations.

    Please help! Bad timing

    Thanks again everyone. No need to apologize for the input, specially when it helped resolve the issue. I will make sure to work on setting the timing now.

    Please help! Bad timing

    Thanks to each and everyone one of you that provided feedback, you have helped me immensely. I pulled the plugs, rotated the engine 180 degrees, reinserted the distributor and BAM!!! The engine fired up after just pumping the carburetor twice. Sounds loud because of the open headers but it...

    Please help! Bad timing

    When you say 180 degrees. Is that a full rotation to where the lines on balancer and tab line up or literally 180?

    Please help! Bad timing

    Did not think about that. Would I just turn the engine a full rotation and re insert the distributor? Thanks

    Please help! Bad timing

    Well, I finally got the engine back in the car after refreshing with all new gaskets and painting it. I also installed a double roller timing chain. I was anxious to get it started to hear the new hooker headers. This entire day was spent on getting it running, no luck. In the beginning I...
