You know what my vote is... LLY swap, then the thing will actually be fast.... Maybe
yeah right :roflmao:
400lbs of boost is like a blow torch going off in the combustion chamber a? You will get er dialed hang in there!:thumb:
Damn sorry to hear this Trent. Cup issues have been haunting me all year, including my hometown event in Columbus, Indy, and the DTS event in Georgia. Fresh cup lifts at each event. In the midst of this, I did try the billet hold downs, but that didnt work out. It will certainly drive you nuts. David at DTS is currently machining aluminum cups for me now. Please give him a call if you are interested(or wait till I give em a test) As for the threaded cups Henry was refering to....they were not ready when my engine was going back in, so I didnt get to use them. I was told that someone did test them(I dont know who) and some improvements were needed. The improved version should be ready soon, and have been offered to me again for testing. I'd like to try both fixes, if time allows.(need to have something that works for the finals in Topeka) I'll keep you guys posted on what I find.
I was not sure if you had ran them or not yet. Was hoping you did and have a option for the issue. Hope your luck gets better also.
So are Billet hold downs even worth the money if they don't do what they're supposed to do?? Don't seem so to me...

If he is selling the "aluminum cups" and has some ready now i will order a set Monday , if its any wait at all it will have to be a winter project and can spin them myself on the lathe or have Randy wip a set up on the CNC , sorry to hear about your troubles also but glad to hear i am not the only one , just wish i would have let out when i saw it leaking :baby: , and as high as boost is this year on the truck i am sure it will happen again .
Sorry to hear Trent. I've battled cup problems for two years now. My problem now is the seats in the heads are eroded from water passing by last season. It is also what is holding me up this year. Last year we used the CAT green sleeve retainer. It held better but we still had issues. We discussed the thread in cups but never could get any made. We also discussed aluminum cups to weld in but had heard some horror stories of how many tries it took to get them right. I only know of one truck running them but I'm sure there are more.
I would have switched heads if I didn't have to cut a new ring in them. My last ditch effort on them believe it or not is ultra copper instead of loctite. I thought it may fill some of my imperfections as well as stretch a bit vs loctite just breaking. I would go LLY or LBZ but I have a bunch of time in extending my harnesses already and an 02 to an 06 swap wouldn't be easy.
We redid the cups last week and got the truck running. We will see how it holds.

I'm telling ya guys, The swap to LLY or LBZ heads is easier than you think. the most annoying part is getting all the brackets if you want it to look like factory. I'm not a stickler in that sense, so I think it was fairly simple and well worth the investment.
I am def not against it but heard it was alot harder with the 01 -02 than the later LB7's ?
i guess well see how it goes and see what we can come up with this winter , and def still considering the LLY route , I have a set of heads here , big cost will be in the injector arena , and having to re-port , ect but would be worth it i guess if it fixed it for good .
damn , sorry to hear this Trent . not that im anywhere near your power but just another thing to worry about
Has anyone tried using the industrial strength loctite with the green spray on primer?
We had some bearings that kept coming apart due to the threaded retaining ring coming loose. Even after installing 2 more set screws the problem continued. So we tore the bearings down and used the permanent loctite with the spray primer. Spun everything back together and they never got loose again.
You have about 30 sec to a minute to reassemble before it sets up and is nearly impossible to remove.
Might be a solution, either way sorry to hear about your truck Trent. Your always pushing the envelope and I enjoy reading your write ups.

Sorry to hear of anyone having issues..... But why do so many with full race only or close to it trucks still run LB7 top ends? Most issues with engine/top end swaps come from getting all the extras and creature comforts to work not just the basics for racing. Thanks for sharing your story Trent, you'll get it figured out.
If the rumors are correct (told to me by Gale Banks?), the LMM head castings have a thicker deck to resist head gasket failure. I don't know if this is true, but I'd research that if I were to do a head swap.
