Thanks, I’m a bit frustrated, the more I research the further I go down the rabbit hole. I’m not looking to spend a bunch of money on upgrades, I just want to get her running again.So yes indeed a C9DE-6090--M design number is atleast a 1969 head and yes it's also one of the large log heads. But it wouldn't of come stock in a 1968 car. The C8DE-6015-B might be a 1968 engine block or it could also be a 1969 you need to find the block and head date codes to know for certain the true year or if the head was swapped out at some time. Best of luck hunting the parts.
Hey thanks, I was trying to use my existing LOD distributor to avoid the extra work and cost. For the time being, I think I will try fabricating a small log to large log spacer just to get me running again while I source out a better distributor/carb combo.if you are going to be using a Load O Matic Distributor LOD (they were used from 1960 to 1967 except in Calif. emissions cars than last year was 1965). For a LOD to work correctly then you need a carb with a SCV Spark Control Valve in order fr the distribtor to work correctly. The carb's that had a SCV were the 1904 & 1908 Holleys, the 1100 Autolites, and some early 1101 Autolites these carb's need to be 1967 or older in most states except again the Calif emission engines that would need to be a 1965 or older. There is also a new carb (Champion) that's modeled after the Holley 1908 that will work with a LOD distrbitor here is the link to the carb info. https://championcarburetor.com/1961...wbrdesigned-for-modern-fuelbfont-p-10770.html
The later model carb's such as the Carter YF, YFA, and Carter RBI are not compatable with the older LOD Distribtors. Do you happen to have pictures of the parts you want to use? If so I can ID them and tell you if they will work togeather or help you find the right parts combo that works togeather. Is there a particular reason you want to use the older LOD Distribitor? The 1969 C9DE also note these newer heads have a larger chombustion chamber of 62 CC this is lowering your compression ratio quite a bit reducing the engines power. I see that you also have a 1965 engine setting there behind the 68 long block, you could use that 65 head which has a 52 CC combustion chamber on that 68 block to get you back to the stock compression ratio of 8.7 to 1 as well as it having the smaller log carb mounting hole that will help you be able to use all the stock parts such as the SCV carb and its spacer to match up with the LOD Distribitor plus with that 1965 valve cover and the rest of the engine painted in factory engine colors give your engine a more stock apearance in your 1965 Mustang if that's the direction your heading. Best of luck in the parts hunt. Edited
Any chance this would be a better option:Hey thanks, I was trying to use my existing LOD distributor to avoid the extra work and cost. For the time being, I think I will try fabricating a small log to large log spacer just to get me running again while I source out a better distributor/carb combo.
I have read those articles on SCV and advice about Duraspark or DUI distributors if you want to run with a different carb. From your experience, tell me what optimal distributor and carb combo would you recommend with my current head? (I looked at the champion carb and it's a manual choke set up - not the end of the world but I'd prefer auto)
I'm liking this one though https://championcarburetor.com/6369...wbrdesigned-for-modern-fuelbfont-p-10773.html
Not sure about its compatability with the LOD distributor though.
