does any one have any exsperience o- ring a block, i need to know what size and type of wire, what distance the groove has to be from bore and the dimension of the groove, width and depth. a local machine shop can do it but i need this information for them.

You can also do the job yourself with the Isky tool.

yes that might be cheaper than the machine shop

Several of the racers have done this.

I think the Drakes, Hambys, Cameron Tilley, Coxes, etc have done it on NA, boost, and N2O motors. Cameron Tilley has o-rings on his turbo motor (up to 22lbs boost and 720HP) - just the block, IIRC.

Tilley has put o-rings on that just hit the fire ring on a nice Aussie composite gasket, which he says works well over 12:1 comp. I think his turbo motor has the copper gasket, though.

i am not familiar with the auzie comp gasket but would o-ring and fle-pro comp gasket work together?

I had my 170 turbo block is "O"-ringed. But that was about 20 years ago. A race machine shop did the work, and I don't remember the specs. I do remember the wire is stainless steel. It has never been replaced. I am now using the Cox Bros copper gasket.

charlie i was told that it takes 3 to6 hrs to set up and cut 6 grooves in a milling machine does that sound about right to you, if it is buying to tool myself would problably be cheaper,no local shop has a 0-ring tool.

That time does not seem unreasonable to me. If you are only going to do one block, it might be better to rent the Isky "groove-o-matic" for $60. I did not see a Purchase price listed on that page.
