Re: Hardness Testingfind
APT, TH56BK, well, yes, I think they are in the right location. He knows the problems with the blanks, and is doing his best to get them corrected. He knows all about where they come from also. I just think this was my best chance, but not guaranteed. I ordered the lifters with the hole in them also. But, these lifters I think are cast in Turkey. Talk to Dave at APT. He also said I would need to be careful not to miss a shift at 5000 rpm, because it would be at 7000 before I could stop it, that should be interesting, cause that wasn't happening before.

Re: Hardness Testingfind
If anybody has a TH5, or Kent cam, I would like for them to look at it and look for a symbol, shaped like a cam lobe, with another symbol inside of it. I am trying to find out if there are more than 2 blanks being made, as I suspect there aren't. I still don't like the fact that there was minor pitting on some lifters, and no cam lobe damage. Even though the lifters tested at 56 Rockwell, I still think something is amiss. Also, I was told by a cam manufacturer in GB that the lifters spinning to fast can cause pitting. I pulled the oil pump and one rod bearing cap, no evidence any metal got thru the oil filter, bearing looked beautiful. If my cam arrives as expected, it may run on the weekend. It is also worth noting that someone in GB, who I was going to get a cam from, lied about when he would ship it, over and over. He had my money 7 days, and still had not shipped it, when he said he would ship it the day he had my money, and provide a tracking number. I canned his butt for lying, because, if they lie about one thing, then you can't trust them about another. And, he was charging the ridiculous price of almost 800 dollars, for the cam, lifters, and shipping. At this price, you would think they would satisfy.

Re: Hardness Testingfind
Searcher,
Too late for me to look at my BPNW TH5 now, it's in the engine.
And it did come from England. Greg told me that he has been using the same cam company since his racing days back in the 70's for cams and that they cast their own chilled iron blanks. He picks the specs, that make the cam.
The only marking that I noticed on the cam was the BPNW logo, but that's not to say that it was or wasn't there.

Re: Hardness Testingfind
I have been following this thread with lots of interest, and being a representative of a company that supplies cast parts, but not to the automotive industry, I have had my share of calls from my end users that had issues.(wont go into details of my issues) Fortunately for me the company I rep took responsibility and made things right...... We source castings from around the world and also in the US, but every day another one shuts down, (sorry but thats the way it is now), and to be honest I dont think the foreign foundries have the capibility or time to really check what they produce, to them its all about the number of parts they can turn out. I, or the company I represent cannot even get a quote on a run of 100 parts or less and I dont think the suppliers for our cars order 100 pieces at a time. First they have to make a pattern of the part, if they they have an original drawing that the way to go, but if you give them a used part either they interpert or they dupicate a used part, in the end The importer pays 50 percent when the parts are shipped and the balance in 15 days, you really cannot get a chemistry back in less than 5 weeks to determine if it correct. So the importer has payed for the parts and assume they are correct and made to spec and unless someone calls with issues they assume all is well. you would think the importer of the part has the responsibilty of checking dimensions, metalurgy, hardness etc, however its the end user who finds out if its good or bad, good thing is the cams go quickly and I hope they get them replaced for free but the labor is not reimbursed, ok after a few beers I am sure I am rambeling on, I am sure it doesnt help if you are replacing part but thats the story
