Just checked it out. It's a special block that Gary originally built with custom o ringed heads. I've got it cleaned out and running with no coolant. Couple of oil changes so it's clean inside. It's running great. Just an internal coolant issue right now. Gotchya, hopefully y'all can get it figured out quick. You are sooooo close to the finish line man.

We had upped the compression and a few other things, and it made great power. But, within a day I got a ticking/knocking and back to the builder it went. Cracked sleeve. I can't really blame the builder, because I had brought them that block (sleeved LS2 block out at like 4.185") which had already been through hell. That said, the cylinder walls were supposedly sonic checked for thickness and of course also checked for cracking. It's hard to even remember all the rebuilds, but I believe it was directly after that when I sprung for that builder's new fancy block (rebranded RHS) and had them rebuild it once again that it started huffing white smoke within one trip. Back it went, and supposedly everything checked out... no blown head gaskets, cylinder walls all good, I thought maybe it was a crack in a head since the head castings themselves had lived through a good half a dozen iterations of that motor. But in the end, I was told one of the decks wasn't square. Still not sure how much I believe that, since a) it was a brand new block, wouldn't it have gone out for machine work including ensuring the decks were square b) if that was the cause, why did they say there were no signs of a blown head gasket or coolant making it from water jack to combustion chamber? Of course, I have no better theory, other than maybe somebody forgot to make the last pass torqueing one of the heads or something. Anyway, been there, done that, bought the t-shirt. I'm sure John will get it worked out, but total bummer when it ruins a trip you've been waiting for so long. -TJ 1 Quote Link to comment Share on other sites More sharing options...

Compression test showed the center cylinder at 130 psi against all the others at 180psi. This was good news to me this morning. Lower compression not lost compression can be a good thing with the symptoms it had. John got the head off this afternoon and there it was. Blown head gasket. The block and copper fire deck ring appear to be fine. Now we pull the drivers side head and give it a look. Going to upgrade the head studs one more level from what they are. This will allow them to torque the heads down a tad more. Nothing wrong with more clamping force. 6 Quote Link to comment Share on other sites More sharing options...

If everything is "square" that will be good news - fast fix - I hope you are using new copper wire - been down the path on Blown Big Blocks, I wish they had a few more head bolts... Always ran either and MLS gasket or dead soft copper head gasket with o rings (and lots of water sealer - the down side of copper gaskets) but its worth it to "push" the boost - I hope its done soon 1 Quote Link to comment Share on other sites More sharing options...

John and I talked about it a long time ago. We replaced one broken VVT sensor but not sure if that was being used for timing reference or the actual VVT system. If I recall correctly, it's a minor boost in performance. Most wouldn't even know it was there in the sand. John has set these up for a few other owners that wanted it but again, it's not a game changer so I'm told. @John@Outfront your input please. Thanks. And I don't mean to be ignorant on my own stuff. Guess I have a lot of trust in John and well its basically "race car" attitude. I am busy with business and life and so is John. Just wanting some Glamis life release. I trust John. Others have done me wrong. My glamis time is a release like I've said before. John IMO has the same experience. It's nice to work with like minded duners in this business. 3 Quote Link to comment Share on other sites More sharing options...
