Another rust combat

[LJ851]

The most common reply from USA manufacturers that I hear is “supply chain issues”

You would probably be fine if you wanted Small Block Chevy Main Studs.

A friend of mine ordered ARP wheel studs for the rear axle of his ‘68 Dodge Charger in August last year and they just showed up this week.

Thanks, I like the look as well, hope I find time to go on with chain housing covers this weekend...
ARP? No, unfortunately not. Same thing everytime, e-shop says in stock, reply on mail says no... I cannot understand the problem at ARP, since almost a year they are really in trouble with availability, some shops say since over a year. I wonder as it's made in USA, not China. So what's the issue? No more steel in the US?

They are saying another 3-4 weeks on through bolts.
Yes, 100% made in America.
Honestly, I'm just glad they are still making these parts for such a small, niche market.

Hi Chris

Well, it may be true for trough bolts (even if I doubt you'll get them in time), but for the case bolt kit it's allover the shops and even ARP themself the fact that they move the date almost daily a couple of days forward and this happen since over half a year. If you can send me the item within 4 weeks I'll pay you another 100USD on top, but if you can't you give me a discount of 100USD

Checked bolts etc. and found little axial play of ca. 1-2/10mm at the cups from valve adjustement screws. Is this normal or wear? Guess not but wonder if really worn or from new like this.

Anyone any idea on this subject?

[reclino]

Play at the cups is normal, I lapped the end of each cup flat on my surface plate to remove any marks from previous wear.

Today I started with workin on the piston pins, machined conical by 14° axial on the lathe to save some weight on the oscillating mass. Made this on the old pins as well without any issue. The weakest area is the piston there, not the pin.



BTW What size of pics do you choose to upload here? With about 4Mb it's incredible slow...

[reclino]

So nice to have access to a lathe.
If I remember I crop pictures down to a couple meg. I am usually uploading from my phone and it's very slow. Almost as annoying as having few people respond to my posts.

Hi David

yes, a lathe is a must when your doing much DIY in my eyes...

[proffighter]

Does anyone has expierence with them, page msroadrace in LA. Sent them a message with questions for a used 965 IC I found on there page and they sent me without any reply a Paypal request for about 15'000USD they have on ebay...??? Normal behavour or WTF?

[Flieger]

I've heard of them but not in a good way, however nothing concrete. Just odd stuff like that and high prices. I'd steer clear.

Thank you. What I've found out as well.

[MGB009]

Super impressive work!

[proffighter]

Still waiting for ARP able to deliver... but in between I can do other things like:

I bought a 964 IC to replace my Blownsix IC (too big for my needs) and the intake air temp sensor from my SDS EFI does not fit. Id did not on the Blownsix where I fitted a threaded insert, but here I wanted to leave the IC as it is. So I made a sensor housing to "transplant" the sensor.

Great solution, well executed!

Some additional info about the sensor above. Cylinder part is 0.1mm thicker than bore in the flange. Mounted with heath shrinking (Cold cylinder, hot flange). Anodized after. Sensor is also press fitted, but to be save as it's something like PA6GF I filled the groove with uv-activated glue. First time I used it, very cool stuff.

Another thing I am working is the fan housing cone (or what it's called). I guess it's not unusual that it have cracks or break completely.

Cut away generous





Filled gap with fiber reinforced epoxy and drilled the hole circle

hmm pics lost...

You are doing really nice work! Your engine will be amazing when done.

I like the anodized pieces you did.

I have done a lot of zinc plating but not tried anodizing yet.

Thank you!

...Then it's time to start

[proffighter]

Proceeded on the fan housing cone. Finish and painting done






I made copies of the air guides out of fiberglas composite





Weight saving of 126gr is quite nice





and finally ready to mount
