Thanks great information nothing to appoligize about. I was more interested in the other motor with 4 bolts per cylinder and the block set up on it just becuse you guys were doing it with stuff that was already out there consistiently etc... Mainly aluminum or Iron block, how much of the block did you fill and the O-ring set up like is it the Stainless wire on top of an MLS head gasket or what. Now what you gave is great and above what I thought I was going to get LOL! Thanks, and if you get a chance to talk to your friend to answer my question I would appreciate it greatly if you would get back to me weather it is in this post or a PM. Thanks again for the info!

I don't think you can use a SS wire combined with an MLS gasket. EVERYONE I have talked to said to you need to use a combo of SS and Copper. You could use an MLS gasket and a copper wire or a Copper gasket with a SS wire. If you use two steels you will seal the combustion chamber but have issues with water leakage.

INSANE But I love it!!!!! Need to send motor to GM to install it in the new supervette or camaro then they would have something to brag about!!!!!!

stevieturbo

Ive used this on a Subaru with an MLS gasket before. It never gave us any problems....although the engine didnt stay together long for other reasons lol. I dont recall how much protrusion the wire had though, but the headwork was done by a guy in the US.
Unfortunately I dont know who.....

To those that said something about the dyno numbers, they use Dyno Dynamics, which if you have any experience on them, they read approx 15% lower than a dynojet.

Great numbers!

That's some serious valvetrain you've got there. I've got a set of those heads for my new engine, but 64cc chambers.

Are you running reciever grooves in the block? Tons of LT1 guys are running hard block with good results.

For those interested here is a vid of GTBMads on the dyno doing 1529rwhp.

Why I think it didnt work was we were using arp standard stud size at the time, and there wasnt enough deck thickness on the lq9 heads and with the boost we were trying to run.
I beleive the heads were moving around so we still pushed water combined with the flex from the block, it was at that time we were cracking the blocks through the mains.

So after filling the blocks and moving to 1/2" head studs is this the setup that help up (double O-ring with copper gaskets) for 75 pulls etc...Thanks. And that video was great loved the sound of the car!

GTBMad

The valve train is pretty decent the solid roller has .720 lift
We used Manley Nextek Springs 300lbs on the seat 700 lbs open the Valves were custom made REV INCONEL, Morel solid roller lifters.

GTBMad- Are you not wanting to post the head gasket info? If not its ok just let me know and I'll quit asking I'm not pushy I just would like to know as it would be good info to have incase I eve decide to make big power etc... Thanks.
Jeff

No its ok been tied up at work

On the standard 6 litre cast iron we used the MLS head gasket with a stainless oring the block was 30 percent filled. 1/2 inch head studs and the red sticky head gasket crap this is what we used on the 75 plus runs

Thanks that is what i was thinking in the first place when someone chimed in that it didn't work on MLS head gaskets although I had known quite a few using them that way like Stevieturbo said etc... I use Yamabond also I don't know if it is the same as the red stuff you are talking about unless you are talking about hi-temp silicone like a Permatex or since you in Ausi I don't know if you guy are using the same manufactures etc... But thanks anyways. Be looking for another post when you guys get back on the dyno again to best that number by a lot etc...
