LQ4/T56 into 2001 BMW 540i

cleaning up heads by hand is completely different from having a shop go through them. You could spend days cleaning and polishing a set of heads only to have a shop pull a vacuum on the ports and find that all of your valve seats leak. If you're confident that they're low mileage clean units then go nuts, but if you're unsure, the only way to tell if they're good is to have a pro look at them. The last thing you want to happen is to bolt them up and have running issues because of random leakdown.

hmmm that is a good point, i may just clean them up myself, then bring them to the shop to have them checked and springs installed when i bring the block. just trying to save money where i can. anyways sorry for the hijack, cant wait to see it back together and driving again!

Top End Assembly
I flipped her over on the stand and went to town.
Brand new OEM LS7 lifters got an oil bath for 2 weeks prior to assembly.

Pre-assemble into lifter trays, which were scrubbed clean and blown out with compressed air prior to use

Cylinder head dowels installed, headgaskets laid in place. I chose an OEM MLS LS3 6.2 headgasket to match the .030" overbore.

Get her down into place, making sure not to snag the surface with the corner of a dowel.

ARP head bolts (varying length design) were torqued in sequence and in 3 stages to the appropriate spec using the required thread lube on the threads, washers, and under the head of the bolts.

Once both heads were on, they got new plugs:

Since I was in a time crunch to get the car done, the rest went together fairly quickly, so I will let the pictures tell the story.

Engine/Trans Assembly and Installation into car
Bolted on a bunch of crap like the front accessories, starter, manifolds, coolant sensors, etc. Cleaned the pressure plate and flywheel with isopropyl alcohol to remove any fingerprints or grease, installed both with ARP hardware, torqued to spec. Joining these two bastards was super fun on my own!

Fired it up and let it idle while checking oil pressure, coolant temps, and general leaks. Some minor things but no deal breakers. The biggest "oh crap" moments were a minor miss due to a loose plug wire, and a leak from the OPSU (replaced with an appropriate plug). As I walked out to hop in and take it for the maiden voyage, it started puking coolant out of the overflow bottle, where a nipple had cracked and broken on a nearly new tank

Naturally only one store had one in stock locally and they had closed for the day, so it pushed back my schedule by another day. However, I tossed a new one in, and took the car to be tuned.
Mileage at the time of engine rebuild for future reference.

Met my goal and made it out to Columbus, OH for Timmayfest - got it strapped down on the dyno (very high heat and humidity).
_DSC3970 by Norbert Ogiba, on Flickr
Fairly disappointed at the numbers - 360whp and 349 lbft. The only change was a more restrictive exhaust in the form of cats, a resonator, and slightly smaller diameter piping. Last year I made 427whp/400lbft on a local dyno. Go figure.

honestly it feels just like it did before the swap - maybe a bit peppier. I don't really recall since the last time I drove it in anger before the motor swap, was last October.
The real test will be to get it on my local tuner's dyno and do some pulls there, that'll be the best apples to apples comparison.

Congrats on getting it all back together!
Your garage cleanliness is a helluva lot better than mine if that's your idea of "filthy"! I'd be thrilled if my work space looked 1/2 that orderly!

My problem is the half started projects everywhere...I get sidetracked and leave crap everywhere ("where did I just put that beer?")
I banged out a quick exhaust job last night on my father's Lexus, so today I'll spend some time cleaning up the garage. Maybe I'll snap some pics.

^ exactly - we had a bone stock M5 that dyno'd there last year, and made 20whp more in identical trim - no changes. It had to be 90F in that shop, with humidity to match.
The best comparison will be running it on my local dyno, where I made 427/400 last year.

Were both dynos Dynojets?
Even if it's "yes", still could be enough swing to account for it. More likely, a chunk of that is from your exhaust restrictions, especially the smaller diameter tubing. If you tune for it, it's hard to go too big on LS motor exhaust.
I know you know how inaccurate butt dynos are. Would be VERY easy to be biased based on the beautiful and meticulous work you do. Really nice job! In for the apples to apples dyno! (Re-do that exhaust!)

i think a lot of it has to do with the head swap too. I couldn't use the 317s I had on before since one of them was destroyed by the valve, so I picked up a set of used 241s which don't flow nearly as well. I am on the hunt for some 799s which I may try some light porting on.

I'm doing a ls1 swap into my 2001 bmw 540i and I was wondering what kind of transmission would I have to run with it because my cousin told me I could get an adapter to mount the bmw trans up to the ls1. Need all the help I can get. Thanks

Whish I had the spare cash. Nice swap !!!
