Default Roadmaster Wagon 6.0 LQ9/4L80E Swap

Hello all, Wanted to introduce myself and a build I am working on, a 96 Roadmaster Estate Wagon getting a 6.0 LQ9 out of an Escalade.

In its current form. A great driver but sluggish.





New Motor/Trans



Discovered where the rats were living



Looks like the engine was outside for a minute



Pitted Cam



Cylinders look good though



I plan on slowly cleaning it up and doing a sloppy stage two, springs, and maybe a turbo. This is just a fun car to give myself a little challenge on something I haven’t done before.

It rides great. I did upgrade to the monroe taxi shocks to settle it down. Before that it would float all over the place.

Great build! Worked on these babies when they were new. Some large sway bars (Impala SS) front and rear help alot. I believe the Impala SS steering box is also a quicker ratio. May as well handle better with that new found power coming soon, lol.

With that amount of damage to the cam, I'd inspect the main and rod bearings for damage; that metal had to go somewhere, and the filter can't catch everything.

But whatever you do, don't look at the cam bearings! (Just kidding - check them, too.)

No good can ever come from looking at the cam bearings.

Made a little progress with getting out old broken manifold bolts. I screwed around with an extractor for about an hour before I did what I should have from the beginning and pulled out the welder.

Also had a little help in the shop today and got the SS2 cam installed and started cleaning up and rebuilding the heads with the PAC 1218 springs.

Waiting on new lifter trays so I can get the heads back on. In the mean time got the motor mounts (KDS-Performance) squared away.

Subscribed, Nice wagon! I pulled an LQ9 Monday for a wagon project, I've got a line on a couple of '89 Caprices.

I had a throttle body 305 1992 model...same color as yours...wish I had never sold it.

It was the inspiration for my 72 A-body LS project.

Good lookin' wagon. Looking forward to your build.

Made more progress on getting the motor buttoned up.



Wrapped that up and moved on to working my way through an HD2 kit in the 4l80E. Had a different helper with me today.

Started tearing down the car today to get ready for the new engine. Having helpers with small hands help with the hard to reach sensors and bolts.

Finally thawed out enough to get some more work done on the car. Engine pulled and ready to start depinning the factory harness. A Holley Terminator X Max is going to control the Engine and Trans. I just need enough of the old harness for ABS, Lights, Wipers, etc...

Good question. He hasn't been around since a couple days after his last post here.
