TR5/TR250 TR250/6 cam grind

Share this page

You need to read what I wrote Brosky. You asked "where do you come up with this stuff", in this case, the OWNER of the company in the UK who grinds them told me on the telephone why he did them this way, does that answer your question Brosky? And, as for the cam gear, from your own picture. Anyhow, the blanks come from India, as I said, and are ground in the UK by ------ Cams. And glad YOU posted the picture, you prove my point, you will notice, if you look very close, the gear on the camshaft is toward the front of the engine, or left in the picture, it should be centered in the opening, thanks for the picture. Pretty well is not good enough for me, also the blanks made in Turkey are centered. If you lay your camshaft next to a Stanpart, you will see it also. Also, if you would do as I said and look at the last 5 lobes thru the lifter holes,I don't think you will like what you see, but that is my opinion. Or, you can lay your camshaft next to a Stanpart and see it. It may or may not cause a problem, if so, you can always blame it on the oil. I am not the only one who knows what I am telling you. Its people like you who are one reason we don't get high quality parts for TR6's. The same goes for you, you are entitled to your opinions, even if you are wrong. AS FOR INCORRECT COMMENTS...,
 
Bottom line:
Paul's car runs and performs great. I think if there was a problem it would have occured during the break in.
This is one person who doesn't need to be schooled.

I suppose, but that doesn't count for where mine came from. Enough said about that, no point going any further.

In an effort to end this amicably, I have taken the original photo and cropped it to better show the gear(s), but it's hard due to the size limitations of the forum to capture all of the detail. And I originally took this picture during the build for an entirely different reason, since my intent was not to capture the gear position. It just happens to be there.

Using the phrase "pretty well" was obviously not a good choice, given your response, so let me rephrase it for you. The gear, in my opinion, the machinist's opinion and the mechanic who finalized the assembly and installation, is in the correct position in relation to the driven gear. Please note that they mate and mesh together correctly. I also double checked with both Bob & Erik and the cam lobes are all in perfect position for the lifters to mate to them, matching the alignment with bores of the block.

Now maybe I got lucky and got a good cam and you didn't. I did speak with Greg at BPNW and he assured me that mine was done in England.

So rather than peeing back and forth, let's drop it here. Or more clearly, I'm dropping it here.

Speaking from a photographic point of view. The camera was not centered squarely over the hole. It is off axis in two ways. So using the photo as the sole source to determine the "centeredness" of the drive gear is inaccurate.
 
Exactly Shawn. I wasn't taking a picture of the cam gear, but rather of the driven gear for another reason. That's why I verified the location with Bob and Erik, even though I had looked down in the block during the assembly process and saw everything on center as required.
 
Looks like you were wanting to show the slight offset orientation for the distributor. Which I can see. But there is no way you can use that photo to determine just how centered the camgear is. No that you were trying to use the photo to prove that.
 
I have decided that there are "some" people in the forum that have an opinion that is of little consequence. They haven't done their homework, and have no idea what they are talking about. In short, they don't know what they don't know, and apparently, don't want to find out. It is ignorant of me to waste my time, and the forums, trying to downsize these peoples ego. There will always be some people who are challenged when digesting the reality of life. I would suggest to those people, if they are not successful in finding a faith based solution, they may want to seek a proper medical solution of some sorts.
 
On other forums that I go on, they have 'ignore lists' that will hide any posts by people you put on them. Do we have that feature here??
 
I know you are all dying with anticipation, after much reading and research I went with a pretty conservative grind with just a little more lift and duration than the stock late TR6 grind, which I guess puts it two steps above the very conservative TR250 grind.

I wanted good low end and also became concerned with some of the wear and cam bearing issues I read about so think I will be happy with the choice.

The engine is also getting raised compression (about 9.5/1 vs, 8.5 stock), some slight work to the ports and combustion chamber (per Kastners competition manual), and the later TR6 dual pipe manifold, nothing crazy.

I am sure I won't be on the road before next year, but will keep you posted.

Duration 250 degrees intake, 254 degrees exhaust, lobe lift .255"
 
Sounds good. Try to document you work with pictures as well. It helps later.
