It's a crate motor with the wet sump and C5 reluctor installed.
The fuel rail covers fit fine. But the oil filler on the LS7 valve covers is shorter. The C5 filler is too long. It was a struggle to get the driver side cover on because of a tab on the cover toward the driver. I snipped it in half and the braided fuel line goes right by the tab now. Look at picture 5 on the right of the fuel line in the hole. It's a jagged cut. I'll get to it. :o I like them so that I can get some gawking from those that otherwise wouldn't know it's a 427.
The torque is amazing. You can lower shift points and TCC lockup making it real comfortable to drive, even with 3.90's and a PT4000.
Mines a level 5 too. I suspect we'll need every level we can get.
Good luck!

I didn't even know the LS7 valve covers had a filler cap (never looked under an LS7 coil cover) good to know since I would have might have cut the hole for the C5 oil filler off center
At least LS7 coil covers don't cost much (compared to LS6) if a mistake is made in cutting them!
Again Gratz on factory looking LS7 install

I don't think I've seen anything this pretty. Williams Performance did the install. The only mods are A.R. Headers and a Vararam. It's otherwise completely stock. It's converted to wet sump.
The car drives like a dream and has lots of B_ _ _ _S. The torque is great so I've been able to lower the TC lockup because of it. You can tell I'm really stoked.
My 364 will go up for sale next week when I can get some pictures.

Virginal appearance ........ and runs like a scalded dog - with a factory warranty.
It is the first LS7 auto I've seen or heard about (not saying others don't exist).
What a great idea

Yes it's a full blown LS7 crate motor with all the factory associated parts, all in working order. This includes the A4 that it is mated with. Thing has a mild cam and runs 10's

I am standing at the cross roads:
MTI Cam only 424rwhp LS6 in my C5 Z.
I want more, but what path to follow.
It seems no matter what direction you take, a big cube motor ends up costing about $12,000.
You either get their in a few steps/installments from a stock 347/364 start - or you just buy the dang thing in a box from GM.
By the time the bottom end is forged, killer heads added, intake, throttle body, tuning etc the LS1/2/6 based car will have about $10,000 in it. (I see all the claims of super-engines for $8000 - but the math never seems to add up).
I alsways keep coming back to a GM LS7 - 500bhp in the box - and if you want more then add a wicked LG cam... and the entire process starts over.
Heck - even a blown LS1/2/6 is a $8000 +++ excercise (and if you want any sort of longevity you need to forge the bottom.. and that adds another $4000 = $12G's again
)
Is this the logic that brought youguys with the GM crate LS7's round to your decisions as well?

I just installed an LPE 100mm MAF. They say there is no power to be gained on a stock LS7. It may be true, but we'll see on the dyno. MAP kpa went up at 6000rpm from 94 to 98 and it had to be tuned for more air. The tires used to break lose at 45mph and now at 55mph. It is colder now, though.
In any case it is easier to tune. The map line is steady, with no chopiness. This sensor is for sure more accurate and I like the look of the setup.
The picture is in the 1st post.
