When Stefko rebuilds the crate at Barrie they change the GM snap bolts to bolts with a wire seal through them. If they changed the crates to have this seal from new would it stop the tampering? Or is it just as easy to get those bolts as well?

Delaware has been doing that (seals) at the dealership before you even pickup the engine. Of course I'm sure Pinecrest knows people who can get around that. But why?
There's all kind of ways to check a crate engine, because, when they're all the same it's easier to check for a particular reading or value in ,on or around the engine right at the track. It all comes back to the tech garage and the skill and equipment available to them. Delaware hasn't been afraid to pull apart a crate if they find an anomaly.

I'm not quite sure I understand Thunder6 's post. The speedshop price for the parts in a GM 602 crate engine are about $12,000. You can buy it mass produced, assembled for $3200. Why would you build one?

Again, If you are going with a built engine or a spec engine ,(and you follow the rules), wouldn't all the engines work out to pretty near the same values for hp and torque. Maybe you would want different engines for different tracks but if you all running the same track???? At least that's what I hear from the engine builders in their pitch to sell product. "Your paying us for the research and development it take to give you the best engine for your track. We've spent a lot of time and effort experimenting and that cost money."
I think it's just BS. Save it for the guys that burp it down the straight track.

And a big shout out to all you tech official and track owners, remember those long, long, long nights at the track watch a bunch of crews tearing down those built motors, listening to the whining and complaining, getting attitude when you hand them a $50 gasket set. Oh, those were the days.

Okay, I have kept looking at the posts on this subject and i have finally decided to add my 2 cents worth.
We build our own late model engines with help from a reputable engine builder and I will continue to do so until I see that the crate program completely under control - which it is not, by any stretch of the imagination.
Pinecrest is saying the bolts are readily available - this is the original post.
I think his point is: How are the tracks keeping an eye on this and what are they doing to keep it under control? answer.......a little bit - but not nearly enough and they had better get off their keyster's before it gets out of control.
If you think you can get away with changing rocker arm ratio's, pushrod lengths, compression ratio or anything else that is very simple to check - you had better check the "best before date" on your prescription because you will not get away with it for long.
Let me say that the crate program has saved several late model classes across north america and anyone that thinks differently had better up their dosage of whatever it is they are ingesting - fact is, the program has accomplished the goal of increasing car counts and for that, I applaud the tracks, sanctioning bodies and racers for going with it.
There have been several suggestions tracks could implement to help keep things in check - the problem is, not 1 track is doing any of these things.
There's pro's and con's to all suggestions and I'm sure that some crate owners will think some of them are completely nuts - well, what do they suggest?
Hey Jay - wouldn't you like to swap your engine with somebody else - even if it's just to see if there is any difference?
We built engine guys are still at the mercy of the technical inspection people and if they tell me to pull the thing apart - I have to do this and put it back together on my dime - what's wrong with this picture when the crate guys may have to replace a set of rocker cover gaskets at the very most.
The problem is exactly what From the Stands sarcastically referred to: 
  And a big shout out to all you tech official and track owners, remember those long, long, long nights at the track watch a bunch of crews tearing down those built motors, listening to the whining and complaining, getting attitude when you hand them a $50 gasket set. Oh, those were the days.
This my friend is the kind if narrow minded thinking that has put this program in jeopardy. The technical people have to start looking closer and if it takes half the night and part of the morning - or even a week to do so - the integrity of the program will stay in tact, otherwise it will only take a couple of years until you will be forced to go back to an engine builder with your crate to have it ............tuned up - just so you can keep up.
I think the crates are the best thing that has happened for a very long time to racing in general and if someone is a couple of tenths quicker that the rest, chances are he will win sooner or later and if that happens to be the night he swaps engines with someone else in the top 5, well that should answer the question right there and then.
I'm almost done - bear with me.
As far as the follow the leader problem that exists at pretty much all tracks lately - there's a couple of reason's for this:
(1) the tracks do need to work on their surfaces to promote passing.
(2) the fields are getting very competitive and everyone is running very close to the same speed - you can be a couple of tenths quicker, but if you lose 4 tenths going to the outside lane................c-ya.

Sorry to take so much space.

Randy I was glad to see your post here on crate engines and the possibilities of some teams tampering with the sealed crate engine.  From your post it seems you do believe the bolts are out there to be had and some teams may be using them to make some illegal changes.  I noticed in the Shaw Motorsports monthly update for April 2007 that you found time to help out a fellow racer with his motor.  Here is the sentence that peaked my interest "Randy offered his services to change the cam shaft and do a general overview for the #31 McWirter racing team.".  Now I would hope that it wasn't the 602 crate engine that has been in the 31 car running at Barrie Speedway in the LLM class this season.  When I first read this back in May I didn't really give it a second thought, but in the last month I have had two people (neither have direct ties to any car at Barrie Speedway) tell me how much faster and more powerful the 31 car looks to be compared to the rest of the cars.  Both observations were made on two different nights by very seasoned race people that only attend the races at Barrie a couple of times a year.  Now let me say this I don't believe you would tamper with a sealed crate engine, but when you start adding things together it sure doesn't look good.

Good to see your joining the party Randy. I totally agree. Swapping engines is an interesting idea, I'm willing. Can I pick the one. I've heard of some crates visiting builders dyno's. I dont know first hand what the outcome was I can only assume they come out stronger or the guys wouldn't be doing it. As far as mine goes it was to a dyno right after we took delivery ( 3 years ago ) just to know were we stood. Valve springs over the last off season has been our freshening expense. So far we're happy with the way things are going with respect to performance. However in hind sight LM's probably should have had the smaller 350 HP crate, this would have created more unity accross Ontario with the LLM's. Cya Friday

Wow,
First of all - I (we) would never intentionally break a rule that was black & white and to consider tampering with a sealed crate would be exactly that.
The engine that I changed the camshaft in was one of their old late model engines that is being used in a modified.
Shawn has helped us out with some deals for the ARP body parts and I simply offered to return the favour.
I have not had a close up look at one of the #602's and being a Chevrolet - I'm not sure where to start because the distributor is at the wrong end to begin with........
This is a prime example of what I was referring to in my post.
I have never seen a set of the bolts and hopefully never will, but then again, I have never wrestled an alligator - hopefully never will, but there's some people out there that get a kick out of things like this........

Cheers,
Randy
