Forgot to mention, The dry sump has vacuum drawn from the CAI, and I'm running the MM restrictor to the SC to limit vacuum, so it doesn't pull air in the front main seal. It's a common problem with...
Look two replies up, I have the HPT file there. If it's still giving you fits, shoot me an email I can send it to directly if you're ok with that? Thanks

Sorry GHuggins, was chasing one thing after the next on here for the past 6 months. Squeal turned out to be the Mighty Mouse catch can pulling too much vacuum through the front main...
GHugginsd,
Yes, it went back to Magnuson and they put in a new rotor set. Since then, I was chasing what sounded like a belt chirp at idle that turned out to be excessive vacuum from the TVS-2650...
Thank you for your help. The false knock in my situation was being introduced two ways, one through the ARH 2" into 3" xpipe that was hitting the belly plate with the green cats, and the driven...
Made 800.3WHP on 91 Pump and 654WTQ. The torque seems a bit low for a Maggie 2650 but it may do to the hub dyno vs the rollers.

After talking to Joe Lewis from Johnson and some concerns about running the 2110SLRs with a cam above .630 lift, (apparently they can come out of the trays or turn in them) I decided to play it safe....
Thanks.....Supercharger has nothing that can touch under it (been off 3 times in the last 60 days lol). Which wideband do you recommend? I have the ARH 2" with high flow cats so 4 total O2s are...
Before I head back to the dyno, I'm changing out the Johnson lifters for the LS7, and the oil pump to a Katech to give my nerves a break. lol I'll let you know how everything goes.
GHuggins,
First and foremost, thank you so much for your help and expertise on this. After digging deeper I found that I may have been chasing nothing after all with the oil pressure. The LT4...

I'm so lost with this stupid car......
I pulled the SC for the third time now and inspected everything in the valley. All DOD plugs are still in and I even added a smaller O-ring inside of the...
Someone @ TSP had mentioned that it's either the DOD plugs or the o-ring valley cover that goes in during a delete, but not both; or it can bleed off pressure. I currently have both in; I just...
It's about the same. It's a brand new LT4 pump so to my understanding, you don't need to use the alignment tools. They are needed for a used pump to ensure it goes back to the way it exactly was...
My oil pressures were within spec on initial startup, and the dyno shop (Kaizenspeed) just wanted to up the oil weight to build a bit more pressure because they thought it was a tad low for their...
Sorry, screwed up the decimal places. Mains = .0016, rods = .0021, and the end play was .006
Here are the attached files. The false knock is significantly less now. Just want to make sure on the oil pressure. If I stab it a bit it jumps up then comes right back down. But when hot it...
UPDATE: I went and picked the car back up and readjusted the pushrods, HPFP lash and found where the high flow cats were still rubbing the belly plate. Kind of disappointed in the performance shop...
So they finally used a stethoscope and found the engine is just fine. The false knock is coming from somewhere else, so they will use the PLEX knock sensor to tune the car to be safe. If anyone...
They reduced by 12.9 percent already which is a lot. This car is loud with the long tubes, but the engine is smooth (no ticking)
I'm fully forged and at 10.25:1 compression. The BTR Stage 2 Supercharger cam requires phaser lockout, so I did the sexy LME front cover with the LS3 seal and solid pinned timing gear. If it's not...
After my winter build project of a brand new LT1 Forged 1000HP build (C7 Z-51) with the below parts; all balanced down to 1 gram by our local top race engine machine shop (Moffit and Bratton). We are...
