No there not, maybe in the pic they look like it.


 



Do you "double-stack" the top two compression rings?  (My top white arrow area)

Except that engine building (properly) is a labor intensive industry.  Who do you think does all the measuring and machining?  Little engine shop fairies?  Not to mention assembly, mock up and parts fitting.

At Woody's level you are not just paying for his labor but for his skill set as well.

You get to ONLY have TWO of the following -- cheap, fast, dependable.

IOW -- if it is fast and dependable it will not be cheap.  If it is fast and cheap it won't be dependable.  If it is cheap and dependable it will not be fast!

Then come election time we can blame them for being on welfare and get re-elected. And employers don't pay in the taxes they're suppose to so taxpayers and workers get screwed again and we come out sweet."

No, the picture is misleading. The top and bottom dots are the same ring package, the vertical line is an anti detonation groove.

These below look identical in size to me --> (the top pic)


Where-as the middle pic (which is the OP's) are not the same size --> (I don't get it yet)
(Unless you put in the top ring and there is an "open" area underneath it -- maybe that is what Woody meant?)



The bottom pic -->

69, look at the SIDE of the piston, not just up front where it's washed out by the flash.  You'll see the top is the same as the 2nd.

I'll get some more shots of the piston tonight. Some good info in this thread so far.

Woody, how much would you trust these pistons up to? What about my rotating assembly?

Depends on how thick the crown of the piston is, but I can pretty much guarantee its easily thick enough for a 400 shot. The crank is fine in regards to power, the rod at most I would put a bolt in it, IF it has the 8740 capscrew currently.

Thank you very much Jim, I really appreciate your input.

At least I'm getting some use out of the pistons. They cost me a goddamn fortune over 6 years ago!

Bore: 4.030
Comp height: 1.255
Pin diameter: .927
Top groove: .064
2nd groove: .064
Oil groove: .218
Piston weight: 469g

1.1" from bottom of oil groove to center of pin.





I'm confused.

You list the same for the 1st and 2nd ring's -- yet from the pic they are vastly different in size?   


I think where the confusion comes from is that the dimensions Ian listed are the sizes of the ring gaps for the rings to fit into. It's not the distance from the dome to the top ring and then between the top ring to the second ring and so on.. Hope this helsp.. Steve

The three recessed grooves that are in the piston for the rings -- all of them are different sizes.


That is where I'm confused.

Oh crap!!!


I just saw it now, finally!

The ring recesses are the black colored looking gaps while looking towards the side of the piston.

I was not seeing it that way before.

Fuckin' brain farts.   I'm sorry


Thanks for setting me straight you all.   Thanx!





Good luck to Blk88GT in spraying a 400hp shot of the stuff.  May he run a safe personal best!
