Damn! That sucks... I wonder if there's a high spot on the block that could've caused the head to crack, and about those soft washers, I would think they should be hard like a grade 8 nut to keep the nuts from galling as they're tightened.
I am yet to do this myself yet, but will soon. From what I read, the torque rating for alloy heads is 30-40ft lbs and cast iron heads 50-60ft lbs. This might be the problem? This is according to vanpeltsales.
don't ARP do a kit for your flathead?.ive allways found their stuff top of the range.high tensile stainless steel available .https://www.arpcatalog.com/i/4/800/0281.jpg .not cheap
Ah that sucks. High spot one of the mounting surfaces?incorrect torque setting ?or inaccurate torque wrench? Weak spot in head? My wife says I have the last choice.
Sucks... BUT, all can be repaired. Your location helps, quite a bit. Bunch of kickass machine shops near you. Blast, dig, and TIG. Good as new, welds dress and all. Put it back together, next weekend. Plenty of time, to keep drinkin' !!
I followed the instructions on the Summit website for the Edelbrock 1126 heads. https://static.summitracing.com/glo...111511161125112611271128-FlatheadCylinder.pdf for torque and sequence. Sent from my iPad using H.A.M.B.
Checked my torque wrench today. Hung one of the cast iron heads 12” from the center of the socket. Adjusted until I just heard a click. The wrench read 27 pounds. Took the head upstairs and weighed it on the bathroom scale...27.4 pounds. I’d say that’s close enough. I’ll hang both heads on it for a higher measurement next. Sent from my iPhone using H.A.M.B.
Could be. I’ll be much more careful this time. I can’t take credit for the TQ test method. I found some stuff on Al Gore’s internet (since he claims to have invented it). [emoji12] Sent from my iPhone using H.A.M.B.
Yes !! So the cast iron heads aren't going back on, then ? Did ya' get 'em fixed ? The Edelbrocks ...
Nope. I have another set of Edelbrock heads going on for now. I’ll address the other heads later. It would be too expensive to have them repaired, so I’d need to do it myself, and I don’t have a Tig welder or a mill. I do have friends with those however. Sent from my iPhone using H.A.M.B.
You have a very cool little truck..! I had a nice little 32 pickup project at one time. I loved the way it looked..
I got my rear gate hardware done over the weekend. I cheated and used MIG to weld the HW to the frame. Should have used Oxy/Acet. I may hit the welds withO/A to look right. Time will tell. Sent from my iPhone using H.A.M.B.
I also used Philips screws. It’s all I had. I’ll swap them for slotted steel. Sent from my iPhone using H.A.M.B.
Neat trick. It got me thinking, that I have some barbell weights that I can use to do the same thing, and on the next occasion when I have to use my torque wrench, I am going to do the same thing. I have a balance beam scale I can use to check if the weights are accurate. Bob
So good to see those pics with the truck out and about, after all the hard work. Thanks for taking the time to share the build.
Nope. Haven’t fixed them yet. Put another set on. I’ll get to that later. Sent from my iPhone using H.A.M.B.
