My Rocket 350 / TH350 sold 2 months ago or so, and I picked up a T-56
from Dallas Texas along with a 12 bolt Chevy rear end with 3.73's.

Then I just picked up a complete low mileage LY6 from a yard in Ohio.
Looking to have it done by the end of Summer hopefully.

LS7 Clutch and Flywheel installed.
Just an FYI to readers, I read up that the "LS7" title is really just marketing hype.
I was told the LS2's in Corvette's (Not GTO's) and all LS3's use this.
LS2 GTO's use the LS1/LS6 flywheel which is different.

Ford PS Pulley mod done.
Posted up the differences against the Dorman 300-201 (far left), Ford pulley (Middle) and factory
Vortec pulley (far right) The Dorman or GM pulley doesn't work without going far past the shaft
and bottoming out coming up 1.5mm shy of lining up right. Some put washers behind the pump, but
that will cause the entire accessory bracket to tilt out at the bottom with that rear PS pump support
bracket there. This image link (http://i46.photobucket.com/albums/f122/Aceshigh22/Olds%20442/2011-06-24171639.jpg) shows you the Dorman/GM pulley deficiency in depth/height.

Sweet! I'ma watchin!

As for the braided stainless...I used this:
http://www.summitracing.com/parts/AER-FCA0620/

And the matching fittings. Only needed two. I have a hard line attached to firewall that goes down near frame rail which is where the braided stainless starts and then it follows the frame rail back to the tank. I'm not using the corvette regulator since I have the 5th gen Camaro fuel module and vaporworx controller. Makes it easy to only run one line from the tank and that's it.

Best of luck!

Soooooo.....we've made progress.

Bought a nice new 180T Lincoln off a Yellow Bullet member VERY cheap.
http://i46.photobucket.com/albums/f122/Aceshigh22/Temp%20stuff/2011-07-25202007.jpg

Bought a plasma cutter and cut out my access hole for the 90's B-body fuel tank that's 23 gallons. Installed the Walbro
255LPH and ran all nylon fuel lines with their connects. Very cheap BTW if anyone needs a reliable EASY to install fuel
system. Also made my own fuel tank straps out of 1" steel stock from Home Cheapo. Major pain in the ass......getting
the bends correct.
http://i46.photobucket.com/albums/f122/Aceshigh22/Olds%20442/2011B-bodyEFItankinstallissues4800x600.jpg

Next I plasma cut out my tunnel for the larger T-56 necessary space.

Test fitting my Chevelle motor mounts with the 1/4" aluminum spacers.
After about 5-6 times of putting the engine in and out we marked the final location for the mounts and drilled the new holes.

Found out I had a bad slave cylinder for the clutch, so I had to buy a new one and rebleed it.
Bought from GM, didn't want to chance it with the Auto Parts stores stuff.
Local dealer that supplies Speed INC hooks it up. :drive:
http://i46.photobucket.com/albums/f122/Aceshigh22/Temp%20stuff/T56slaveapart2.jpg

Then I discovered that my engine and trans wouldn't mate......my clutch was slightly misaligned.
Good thing I took it apart too, my 4 year old shoved a 6 in long intake bolt in there somehow. :rolleyes:
This was last weekend......all ready to go.
http://i46.photobucket.com/albums/f122/Aceshigh22/Olds%20442/2011LST56matedOct.jpg

Engine and trans are now mated and in the car finally.
Just gotta get the degree finder from a store and measure my driveline angle and adjust.

The motor mounts took some time, but finally figured them out.
Used all stainless and superglued my nylon lock nuts to a washer to put it
in my ratcheting wrenches and get them on from inside the K-member.

Chevelle mounts with 1/4" aluminum spacers so I cleared the steering linkage.
I put the order on here that I installed each bolt. Pass side I made an access hole like this one too.

Engine is in the bay, straight, and perfectly balanced.

T-56 Tremec 6 speed is finally in it's place as well.
This part required the use of a 2x4 to lift the trans up and relocate the trans crossmember
backward about 6 inches or so. Had to disconnect the parking brake cable from the crossmember as well.

Now I just have to find the proper angle of the driveline and get a mount for it.

My core support, hinges, radiator cover all just got blasted and powdercoated semi-gloss black.
Radiator is here, and my LSX Harness rework is all done, so it's just a matter of time now.

That will be a sweet ride when it's finished. I hope you didn't get the Walbro pump off ebay. Almost all of them sold there are cheap Chinese knock offs and fail before they have many miles on them.

Just to clarify the 2004 GTO is a LS1 and the 2005-2006 GTO's are LS2 and the flywheels are different. I am sure of that, I am not sure of the other models you mentioned.

If the car is going to be lowered, you can safely install the transmission as high up as the floor will allow. The part that will hit first is the slip yoke where the u-joint is. You can also make the mount a little lower and then use shims to raise the trans if you have to.

I'm going to try and reuse the original one I cut out but add 2-3" of steel to each side.

If that proves to be too much of a pain in the ass, I'll put a whole new tunnel in from the gauge steel I need.

IIRc someone said it's 16 gauge.....but not sure.

Nice looking car Aceshigh. I have a 1972 Cutlass S that I'm in the beginning stages of getting things together to swap in a 2000 Corvette LS1. Did you do any engine modifications other than the LS3 intake package? I plan on doing a cam but I haven't foud the right grind that will suit my needs.

Negative.

I'm installing it as a stock motor to preclude troubleshooting extra issues initially.
I want to make the install as simple as possible.

After it's installed, I'm going to do a cam and spring swap in the near future.
Gonna play with it as is for a season.

Sorry guys, I have been so busy with my new house I moved into last summer.
An old friend just moved back from St Louis who has re-ignited my interest in completing the car finally.

We took out the rest of the interior this weekend, and rear harness and started routing the new whole
car harness. I had to weld up the old fuse panel firewall hole, and I just ordered a sealed grommet set
off Ebay. I have my giant wire wheel hooked up to my DeWalt so I can wire brush down my whole
floorpan of the interior next. So I'm sure this next weekend some new progress will be posted up.

I can tell you this, my welding skills SUCK BALLZ now that I haven't done it in a year!!!!
I had a buttload of grinding to do with all the SNAFU spatter. I'm taking the car in to have the tunnel
fabbed. I sealed it over with a coat of RTV silicone. Didn't realize it's been 2 years since I started this.... :cry:

how are you going to tackle the clutch pedal?

What do you mean specifically ?

I ordered an OER clutch pedal assembly from one of the Oldsmobile parts vendors.
I've already installed it. Nothing major, but once I get the electrical done and I finalize
my fuel line I can begin testing the clutch linkage out. You can see the special powdercoated
clutch adaptor plate I purchased already sitting on there. They're only $30 off Ebay now.
They were $80 years ago when they first came out.

What's up Speed ?? I bailed out of Nastyz. Too much drama with my homo midget stalker and Admin doing nothing but complain when I responded to his little man BS. Had they just banned the troll I'd have stayed.

I got my harness done from the McCullough brothers. So you're doin an LSX swap??
http://www.lsx-harness.com/contact.html

I honestly can't comment on how well mine was done .....YET since it's not in my car. However they came highly recommended. I used Speartech the first time on my LS1 and I didn't think it was worth the extra premium of 2x the cost this round. One complaint I do have is you never get a final schematic of how this is all wired to troubleshoot it later down the road.......from any company.
Good to see you're back working on it. Been putting a lot of miles on mine.

What's goin on Gary ?? Long time no see yeah ?? :D
I'm still going to be doing the samething with custom door panels like you did eventually. Have you been keeping tabs on your MPG's with your 5.3L 4 speed swap ?? I'm curious how well you've been doing since I've got the 3.73's and T-56.

I have just got my boot in the arse from my boy who is off all summer to get this car finished. We're wiring it up already, guess he didn't want to wait til the weekend knowing that I'm a slacker. LOL We should have it completely wired within a week or so.

ON mpg, I'm at a little better than my truck, so the olds is getting around 22 combined when I'm not hard on it.
I did an experiment years go with a SBC/700R4. On the highway, the 30% reduction in rpm with the OD have about 10% better gas mileage. So don't expect anything better than low 20s.But either way, it's a great looking cae and fun to drive.
On the door panels, every show I've taken the car to, some Olds guy asks if they're off a chevelle, gto, etc. lol

Yeah, I here ya on the drama over there.. That's why I mainly lurk and search for info over there..

I'm getting an LS1/4L60e combo, with the harness, computer & front accessories out of an 2002 Camaro from JJFarmer on Nasty.. Says it came out of a Florida Hwy Patrol car. High mileage, but it being in FLorida it's all hwy and those cars are maintained.. Motor might even be rebuilt b/c it's over 100k.. The mileage doesn't bother me too much b/c of the way these are built.. Much better overall over a Gen 1.. I was going putting together a 400sb/200-4r build and gonna get it all done at the end of the month, but I saw his motor and the price is right (under 2k for the package) so I jumped on it. Just gotta work out the shipping. All the parts for the 400 are getting returned, 400 going up for sale, then I'll have the funds to install the LS1 into my '78.. I believe I can do it for another $2k.. Basically the same $$ total I was putting into the older stuff..
Just researching everything in the meantime till I get the motor and old stuff gone..

I was gonna go with Speartech for the harness, but they told me 4-6 weeks.. I'm not crazy about that.. Painless wants over $700 for a ready-made.. Not spending that.. There is a guide somewhere with all the info to modify the harness, so I might just tackle it myself.. Gonna send the computer to Brendan at LT1swap.com.. He charges $75 and a quick turnaround..

Fuel system, everything from a Grand National will bolt right in to my car.. I can get it all for under $400 from Rock Auto.. Get the Corvette filter/regulator.. Just gotta work out the lines and fittings at the pump side, and rail side.. and the other headache will be the exhaust.. But it's not as bad as I though it would be.. All the F-body stuff should fit with the right motor mount adapter plates from CarShopinc.com.. I think once I gather all the parts, and get the harness done, I can bang it out in a week or so.. Need to figure out how to get my speedo to work.. No budget right now for new gauges.. See how it goes..

If you have any info on the fuel fittings, I'd appreciate whatever ya got..

Good choice on the CarShopInc plates, IIRC that's where I sourced my newest ones'. Cheap prices, good quality vs the competition.

If you have any info on the fuel fittings, I'd appreciate whatever ya got..

Depends on the fuel line you're choosing. There is a diagram in the Conversions & Hybrids sticky of the 67-69 Camaro section that's got info you can use.

I opted for the newer Nylon fuel line modern vehicles use because my 442 is a full frame vehicle to hide the fuel lines in. I forget exactly what the underbody of the 78's looks like after the front subframe to run fuel line, so not sure but most modern vehicles aren't full framed either so.....ya know. The Nylon fuel fittings are $2 a pop and look identical to the Russell AN fittings, except they're Nylon. If I opt to go over 500hp down the line later on I'll swap these lines out for hard lines, but for <500hp it's fine.

I bought the Nylon tool kit to install the fittings properly but it can be done with some ingenuity and a caulk gun, someone posted before. I can find it if you need that info and plan on going with Nylon lines.

Got the fuse block in tonight, and wire wheeled out my floorpans after a 17 hour shift. Sucks, might have to work all weekend.....but I love the OT $$$
