ARP Rod Bolts

[Jerry C]

Bob,
Put me down for 2 sets. I have no problem sending my money up front. Let me know how much it is and how to pay you. I do understand you will need to pay for all of them up front.

[RallyBob]

I think we're already sold out basically. I count 9 sets, not including my own 2 sets, so we're already over by one set.

Let's see what the current prices are. Metal costs have gotten ridiculous lately.

Bob

[tomking]

I will take a set Bob. Thanks.

[GTJIM]

Whatever the price this has to be too good an opourtunity to miss!

I NEED one set and would LIKE three sets - what ever the cost ...
Just let me know about the price and I too will send money up-front.

Many Thanks, Bob - I am sure they will make as many sets as you can sell once they are set up to do them ......

[N61WP]

I'd take a set too for future need and be more then happy to pay you up front.
Sounds like we are getting closer to twenty....

Yeesh....my credit card will not be happy about this!

Okay, typically I don't like to accept money until the parts are done, but in this case I may have no choice. Just too much for me to front at once otherwise. We'll decide once I have prices.

Bob

[automata3.0turbo]

yeah get us those prices. i dont like to agree to anything until we have concrete info.

[jeff denton]

Why only ten sets? Can't we get enough for everybody? I'd like to have a couple sets, too! I'd pay up front gladly, also. Geez, we've waited years for this to come around again!

[wrench459]

I'll like a set also, if the price is fair and I understand the cost of tooling up
for a special run of parts.

[RallyBob]

We're up to 20 sets already. I may have to have 30 sets made by the time this is done.

Bob

[oldopelguy]

Are we talking still in the $70 a set range or dramaticly more? That's still $10 a bolt, after all. I'm in for a couple sets too, if they don't get over $85 a set or so, one set if they do.

Let me know if you need some up-front $ too, Bob.

No idea yet Stephen. I am waiting for a return call next week with current prices. They haven't made a batch of these particular bolts in almost 7 years.

Bob

[cherokee]

Put me down for a couple of sets, I will gladly send the payment + estimated shipping in advance.

[RallyBob]

Just got off the phone with ARP again. We're working on a deal for perhaps a *massive* order of rod bolts. If it happens, the prices will be very good...maybe even cheaper than before. It would also encompass other products for the CIH engines.

Potential items available from ARP specifically for Opel CIH engines:
*1.5/1.6/1.7/1.9/2.0/2.2 rod bolts (the same)
*2.4 rod bolts (shorter than all the other CIH rod bolts)
*head bolts...studs are a bad idea because of access.
*main studs
*Maybe rocker studs, but they would be very expensive due to the large number of machining operations required.

Should know by Friday of this week on the rod bolts however.

Bob

If price was right, I would be interested in set (or two) of rod bolts/ maybe head bolts? Can't hurt to have set for future needs. Let us know price.

I bought the Keith Wilford "2nd Group Buy" of head bolts. 2nd group was slightly different than 1st, with lower grade strength of one length of bolts. Still haven't used then.

Thought I saw OPGTS is NOW selling head bolts?

Hi Bob,
Depending upon actual price I'm interested in:
2 sets of 2.0 rod bolts
2 sets of 2.4 rod bolts
2 sets of head bolts
Thanks again for this super news/group buy!

I would think that getting prices on this stuff would be like hitting a moving target not knowing the amounts we are looking at ordering.

I am very intrested in rocker studs, Stan told me he broke a rocker stud once already and I am running the same valve train setup, I would as well be intrested in head bolts.

If they (ARP) can give you prices that are in the ball park that would be good enough for me.

Like I said a few posts up, I will gladly pay in advance....help keep that Visa from bleeding too much.

[jeff denton]

Nice work, Bob! I would be in for a set or two of anything made by ARP that fits the 1.9.
Stan was breaking rocker studs because of ridiculous spring pressure, according to Roger. Regardless, I would use new ARP rocker studs if they were available. It is all good, cheap insurance. You know, when you're sitting in lineup before the race, some of the things that go through your mind, like, are those old bolts out of a junk engine gonna hold up another fifteen minutes of 7500 rpm?
Please remove this thought from the list of pre-race mental jitters...
If one of the problems in making the rocker studs was all about the oil hole, I would be glad to have them without it.

Jeff, Remember this posting? I have drilled one of these ARP studs from Crane and they will work with a bit of modification ...

Bob, Great work! I think both ARP and your good self will be surprised how big the demand for these CIH fastners will turn out to be ....

[jeff denton]

Ah, yes, I do recall that you have been in that territory before. Thanks for the reminder. This is do-able.

[RallyBob]

Ironically this whole 'stocking Opel bolts' idea was his, not mine. I really just need to show there is sufficient demand to warrant production runs and catalog numbers of these bolts, and they will stock them. No cost to me after the first batch of rod bolts. In other words, I buy the first 400 bolts, they will make another 800 and put them on the shelf. I can supply him with a list of various companies, both here and abroad, who might have a desire to sell these items. That would be the clincher.

Fingers crossed, don't want to jinx it...

[Mach1Tom]

I'm sure I'll be needing some bolts of each type to add to my parts stash & my next engine build.

I know the springs in that motor where crazy, I also have a set of slightly softer springs he told me to try out. I already have the softer springs installed, but he had those hard ones for a reason, I would like to play with them, if the studs let me I am all over it.

Whats the saying in for a penny in for a pound.

That's the smart way to look at it, but I think the company that I work for operates on the opposite end of that philosophy, Penny-wise, pound-foolish.

Anyways, Head bolts and rocker studs are actually more important to me. I am not impressed with the products that are currently available.

The reason the springs were overly stiff is because the machinist in Texas who freshened up Roger Wilson's head decided that, like any Chevy(?!?), the springs that were in there before were too soft and they needed to be much stiffer!

Realistically, with the small stem valves that Stan's head had (if we are refering to the same head), no more than 250-260 lbs of open pressure is needed to run the rpms the engine is making power at. Now over-revving is another issue altogether, but IMO running an engine 1500 rpm past the power peak for the sake of revving is just abuse....

For what it's worth, a 1.8" valve with 8 mm stem, 1.25" springs, titanium retainers, and a .548" lift/272* @ .050" cam will hit valve float at 9500 rpms with 105 lbs seat pressure and 255 lbs of open pressure. If you're revving it less than these numbers, or have lighter valvetrain parts, then any more spring rate is just wasted energy, and prone to breaking/wearing out parts!
