  1. Was measuring the rod journals on the 48 crank to see if any were tapered, and causing the pistons to be cocked on top. Measured vertical axis first with rod BDC and then measured sides. Nothing strange enough to cause the problem.
  2. Concerning frustration, here's my accidently knocking my light off the block while measuring stuff. Picked it up and it wouldn't work. So I decided to finish it off. Was beating the crap out of it on the concrete. There Mr Light, now I know you won't work.
  3. Yeah, I stayed quiet on that one with raised eyebrow. It wouldn't increase compression any more than it was originally. Start it knocking..sheesh. Only thing with me I was trying for a piston to deck measurement freebie to see variations. ? Nothing is more enjoyable than adding work to someone else's tasks. ?
  4. I'll hijack it...here's me about a week ago with my BCC removed. Normally I'm prettier.
  5. Just make sure to drink enough water. About a 16oz every 1/2 hour. That's what I bought, the copper nickel line. And the cheap double/bubble flare tool.
  6. Sounds like some of the days I've had..
  7. I was considering the 195F stat. Bought the 180F one but still a long way from getting it running. Didn't know how that 195F stat would do, being 17F from boiling. If more people were saying they had used it with success I would. Let me know how it goes.
  8. Startled me. Thought you had another freeze plug blow. I'm going to use the suggested JB Weld, just need to find how much of a bead. I'll probably add a shroud later when I get this motor running. I might run mine with water for the start up and first 30 minutes, then see if any crud comes out, no leaks then use 50/50 antifreeze.
  9. I was checking before I give the crank to the machine shop. Don't understand what "draw in" is. They were tight, but installed easily and I torqued them to about 80 ft/lbs.
  10. Yep. I was using .035" as minimum compressed gasket thickness (worst case) after surveying several posts. They were ranging from .040-.050 compressed. Plus there is .02" heat expansion and stretch figured in. If the pistons varied a little and all were below deck and made sense I'd let it go. But some pistons (#2 & #6) are proud at front and flush at rear (not level). Difference is just too much for perfectionist me.. #1 .012" BD and 2/6 .010" AD. Still studying on it.
  11. Change the tire size? https://www.jeepfan.com/tech/tire-to-rpm-ratio-chart/#:~:text=If you’d like to know your speed at,diameter to the linear distance the tire travels.
  12. Until one of the proud pistons taps the head. Appreciate the info though. Looking for explanations.
  13. Got to run to a lunch invite from neighbors, but go to thinking about rotational forces on the crank when I was trying to get the nut off. The #3 was fixed, front was having force applied. Might have twisted it. It would rotate in mains but be off. Will think about it.
  14. I was kind of doing it that to find TDC with my dial indicator. Kept going back and forth and watching the point where the needle didn't move. Would find the middle of arc of where I was turning the crank back and forth about 1/8" with no needle movement. I'll see how much a degree wheel is.
  15. That's my question, how much tolerance is there between all cylinders/pistons on this type engine and maybe on modern 6 cylinder engines. Seen one site say .001 usual, worst .005 on some imports. Someone else told me what he saw from a builder's site .010" (seems a lot).
  16. Does the degree wheel need to be specific for our engines? Know which one?
  17. ? ? Probably can't with my experience (lack) and lack of tooling.
  18. Was checking other sites. Discussion on a V8. TheSamba.com :: View topic - bent crank? deck height differences One thing I noted, the crank turns easily in the mains with them torqued down. You would think if it was badly bent (by me) it would have affected that. The crank has been turned .020. One guy suggesting that if you turn a bent crank it can rotate easily but have different strokes.
  19. Think when I stuck the wood block in the #3 cylinder to keep the crank from turning, to get the crank nut off (old post), I warped the crank. I know I bent # 3 rod, but replaced it. I know the top of the D46 block is perfectly flat, I measured it. Thought it might not be parallel to crank, but after checking, think crank is warped. Been storing crank horizontal on trunk of my 58 Dodge. Varying opinions on internet whether this will warp a crank. I took a # 1 rod (odd), put a piston on it without rings, and installed it on # 1, 3 and 5 journals. Measured piston to deck clearance, center, front & back of piston. Then I took the same piston, took same bearing inserts, and put them on a #2 rod and checked 2, 4 and 6. I used my dial gauge to get TDC on each piston. Kept creeping crank back and forth several times looking where dial didn't move, across about .002-3 on gauge. Here's what I got. # 1 - .012" below deck, center and front (pretty even). #2 - .010" ABOVE DECK on front, flush at rear. #3 - .009" bd, center & front (even). #4 - .000" flush front and rear. #5 - .003" bd center & rear, #6 - .006" Above Deck at front, flush at rear. Got another car in the woods at my father's house an hour away..oh well.
  20. So, that doesn't make sense. After #2 was off, I used the bearing inserts from the first rod I used to check #s 1, 3 and 5, thinking maybe it was different. Still did not help. #2 still .010 above deck at front (of piston), almost flush at rear. #4 - flush at front and rear of piston, # 6 flush at rear, .006 above deck at front. Anybody ran across this before?
  21. I'm going bonkers. Started checking the even pistons using the #2 rod. First check on # 2, expecting .011-.010 since # 1 was .012". Freaking piston is about .010 over the deck on # 2. I'll check #4 and 6, to see if the piston gets higher towards the back (block lower) as 1 ,3 and 5 did. Reckon I'll start comparing rod lengths, I'm using the same piston as I did with the previous check. Bryan
  22. On Rock Auto? You must have got the last one. Shows out of stock now.
  23. I ordered that same model and compared it to my 48 Dodge starter and it looked identical.
