I definitely considered trying that. Does your cross member have the upper arms that bolt to the top of the frame? I was afraid I wouldn't be able to rotate it into place with the transfer case attached. Was hoping to install the trans and t-case together as a unit, but I couldn't figure out how to do it with the cross member in place.

Thanks for kind words. Your thread and a few others keep me motivated to keep picking away at this project! This forum is the best.

yes, I install as a unit, trans. and t/c. seeing as I have a 4" lift, it rolls under nicely, easier to put on trans jack outside of truck, and roll in place. Diagonal supports can be installed later. As you are, I'm a one man show, so any mechanical advantage I can gain, I use

I agree, great group of guys with tons of knowledge and experience, all willing to share. and yes, I use the builds to keep me motivated

BTW, I use exhaust manifold studs to line up, and install my t/c to trans. you can take them out later or leave them for future installs

Ahh, I see now. My upper frame brackets are still riveted to the main cross member. I should have drilled those out and made them bolt on the first time I had it out!

Cheers

I convinced my Dad and brother to stop by on Sunday to attempt getting the LQ9 installed. Got started around 10AM and we didn't wrap up until 4:30 in the afternoon.

I decided to put the motor in, clamp the cross member in place, then I pulled the motor back out. Drilled and bolted in the cross member, then dropped the motor in for good!

Plenty of clearance around the Dirty Dingo x-member, but need to extend my bump stops to make sure it stays that way!

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

Update time! Per the thread title, I've basically disappeared for a while. Kids and life have limited my Blazer time, but I was expecting that.

Over the summer I did a few things. Cleaned up the intake and installed the top end components.

Had to make a new power steering line for the high pressure side. I had a short section of hydraulic hose made up with compression fittings. Cut the formed hard lines where needed and installed. Not many people document this, so I thought it might help someone.

Shortened the low pressure line and I also had to plug the 2nd low pressure reurn line on the bottom of the pump. I believe that's used for hydroboost applications which I hope to convert to in the future.

Also roughed in the braided line for the transmission cooler. Basically hoping to wrap as many little jobs as possible in the engine bay before the front clip goes back on. Torque converter bolts, headers, and wiring clean-up coming next!

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

Stole another hour in the garage tonight. Installed torque converter bolts and my headers. Headers are the ls swap Doug Thorley #THY-324Y-C. Fit overall is fantastic with one minor clearance issue.

Look fantastic. Still have a pair of ls3 manifolds, but I'll be selling those now that I've confirmed these fit.
Nice clearance between frame and transmission. Plenty of room for the O2 sensors.

One clearance issue though. Driver's side header only clears the firewall by about 1/16" on one spot. May be able to loosen my mounts/crossmember and 'clock' the motor. I might be able to drop the driver's side and raise the pass side.

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

I'm not dead, but my predicitions for a slow progression with 3 little kids have come true! I had to pull of my beautiful Doug Thorley headers and replace with some LS3 camaro manifolds I already had. I just couldn't get the clearance for the headers without beating in the firewall. If anyone is interested in the headers, shoot me a PM!

I blasted and painted the manifolds with POR's High temp gray paint and baked them in my grill to cure them. They came out decent and will do for now.

Also got my Lokar style shift linkage hooked up to the 4l65e. The detent isn't fantastic, but I'll need to adjust it once I'm up and running.

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

Also swapped out the driver's side door hinges with an old pair I had lying around. Had to machine the slots a bit to get enough adjustment, but now the drivers side door is closing nicely and the body lines are a little bit better. Definitely not perfect, but at least I'm not using the latch pin to hold the door up now.

Next up was to rebuild the steering and front end a bit. The driver's side ball joints were shot. Replaced driver's ball joints, bearings, and seals. Also upgraded all the original steering components. Tie rods, drag link ends, ball joints....almost everything appeared original!

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

Next up is wiring. Started laying out and plugging in my BP Automotive reworked harness. Everything on the motor is now plugged in. Just need to plug in the trans. connectors, O2 sensors, MAF, etc. Wired up my temp. sender to the original green wire and also connected the purple starter wire. Trying to pick through some of these things before I drop the front clip back on. Hopefully that will happen soon and I can start working on the rest of the wiring and PCM mounts.

Dropped the old gas tank last night. It was dented in the back and the gas gauge wasn't reading right, so I'm replacing it with a new one and a new sender.

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

I drained what was left for fuel and used a cold chisel to cut off the old filler neck. Was slightly concerned about sparks and vapors, but I went for it anyway. Worked pretty damn good and was off in just a few minutes.

Heated up the solder and pulled off what was left of the tank from the unreplacable filler neck. Rumor is the neck on the replacement tank is brazed on and should be swapped by a professional shop. I'll be looking for a radiator shop in the southeastern MA area if anyone knows one. Don't seem to be many around any more.

Rubber vent lines and filler hose are pretty much shot. I'll be replacing all of that when I put the new tank back in. I'll be running an external Walbro pump and vette regulator with factory style nylon lines and quick connects. Should have gone with the 87 style tank, but I already had the LMC tank from before I started the swap. Hope it works!

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

Nice write up, good work. If I remember there is a place to but the filler hose as it is an odd size

I found a shop in Rochester NY.

Thanks Jaros! Yeah, the filler neck is 1 3/8". I just ordered some from fillernecksupply.com. Everything was so dry rotted, I'm planning to replace all the vent hoses and clamps. The one time I filled it up before I started the swap, gas was pouring out of the 1/2" vent hose!

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

Just reading through your thread and noticed something. You're correct that the power steering pump with 2 ports is from a hydroboost equipped truck, but if you're not running hydroboost, then you need to cap off the upper fitting on the reservoir and plumb the return from the steering box to the lower one. Running it to the top fitting can cause fluid foaming, which is why they return the fluid to the bottom of the reservoir.

Wow, thanks for the heads up! I capped the bottom port and couldn't find much info on how to plumb the dual return pump. Should be a bit of a challenge to make the turn around the frame without hitting the pulley! Would like to convert to hydroboost eventually though.

I have some family stopping by to help put the front clip on tonight. Guess I'll have to fix it the hard way this weekend with the inner fender in the way.

I would leave the inner fenders out till last, lotsof room to work on the engine if you take the wheel and tire off as well

Re: 3 Kids, 1 Wife, and 1 Lonely Blazer

Just came on to vent. Been trying to realign my front clip for the past week or so. I'm not a body guy and this truck is kicking my ass. Hood and drivers door fit like crap when I bought this truck. Got the driver's door closing nicely, but I can't get the hood to fit well. I know the gaps on these trucks weren't great from the factory, but 46 years of use and abuse have me scratching my head. Frame doesnt seem like it took a hit and body seems reasonable square on the chassis. Just for giggles I also installed a new grill shell to add to the pain. Lots of chips in my paint, lots of curse words, minor progress. Think I need to reset my expectations and just shoot for panels that latch properly even if the gaps suck.

Once I get the hood latch straightened out, I'll post some pictures. Just needed to blow off some steam!
