RichBad Posted September 20, 2018 Author Share Posted September 20, 2018 Called today and they are mid way through repairing it, they said it’s no problem. Still have my doubts but they said they will pressure test when done. I asked if they will torque it down any they said only lightly. I asked them to fully torque it for the pressure test as I don’t want to rebuild it all only to find that it goes when I torque it up. I’m nervous but I also don’t much like the other option of starting almost from scratch on another block. Link to comment Share on other sites More sharing options...

RichBad Posted September 20, 2018 Author Share Posted September 20, 2018 Good point - I haven’t. The 45lbs I was told seemed reasonable any less seems quite low for a head - anyone have experience with lower torque on these heads? Link to comment Share on other sites More sharing options...
chistech Posted September 21, 2018 Share Posted September 21, 2018 Torqued the 7/16-14 head bolts on my 32’ Olds flathead 6 to 42# with no issue but all were new grade 5 rolled thread,high head bolts made 20 years ago. Like your motor, the majority of the holes are open bottom into the water jacket. 1 Link to comment Share on other sites More sharing options...
RichBad Posted September 27, 2018 Author Share Posted September 27, 2018 (edited) Picked up the repaired block today and they said it will be all good. They just repaired the large two cracks but not a couple of small ones on the front - they said because it was quite thin walled it would weaken it further and because the small cracks go into the stud hole which is sealed with the studs it would not leak. They torqued it up and pressure tested it to 45psi to test the repairs so I guess it’s good. I also spoke with the guy who did the repair and he seemed to know what he was talking about. He was also surprised that it had cracked as he did the initial crack and pressure test - I asked him if the old studs were in when he did his checks and he said they were. Really makes me think that removing the old studs caused the damage (or at least weakened it) as the marks on the studs look like they took a huge force to remove. Time me will tell - they did quite a neat job with the repair and luckily Matt gave me some extra paint so I could patch it up.

JayG Posted September 27, 2018 Share Posted September 27, 2018 Is that still a crack showing left of the bolt to the cylinder wall? Link to comment Share on other sites More sharing options...

No, it’s just a stain - I think from where they pressure tested it - definitely not a crack. Link to comment Share on other sites More sharing options...
RichBad Posted September 28, 2018 Author Share Posted September 28, 2018 Right, back to where I was a couple of weeks ago! Have torqued up to 20lbs and will leave to settle overnight and next step tomorrow. So far all good ? 3 Link to comment Share on other sites More sharing options...

RichBad Posted October 4, 2018 Author Share Posted October 4, 2018 Engine back in the car. Hoping to start it up this weekend. 3 Link to comment Share on other sites More sharing options...
Spinneyhill Posted October 4, 2018 Share Posted October 4, 2018 After you start and idle it for a while, you will be leaving it full of moisture with all the assembly lube removed. Do you really want to do that? If so, when you are ready to shut it down, squirt a bit of oil down the carb to make some smoke. It will put some oil on the valves to prevent them sticking and oil the upper cylinders. 1 Link to comment Share on other sites More sharing options...
RichBad Posted October 6, 2018 Author Share Posted October 6, 2018 Well it started first time - almost - just had to pull the mixture lever and she fired straight up. Got to check/adjust the timing and mixture but she’s running pretty smooth. And doesn’t doom to be any leaks so far... will load a video when i can figure out how to shrink so I can upload. 3 Link to comment Share on other sites More sharing options...

RichBad Posted October 6, 2018 Author Share Posted October 6, 2018 Bob has sent me a bit for the gearbox which is on the way. Otherwise I probably could:). I was thinking of driving over in other car just to see some of the other Dodges. Is there somewhere everyone is meeting? Link to comment Share on other sites More sharing options...
