Builds A 1994 80 Series gets an LQ9 GM V8

[Overland Tailor]

Nicely done using the stock GM tensioner for the accessory drive belt vs. an aftermarket solution like we see on some of the Jeep Swaps...

Best,

The GTO engine covers don't sit quite right on this particular engine due to some differences in fuel rail size etc. Here are a few tabs that we bent up to make them a bit more secure and improve the fitment.

Now you're just messin' with us.

Here is the proposed path for the transmission cooler lines:

...bending up a couple of brackets to keep everything tucked up tight:

...bending up and mounting hard lines:

Super clean! I might have missed it but I take it your not running an LS2 intake?

 

[yotasavg]

very clean build, me gusta!

Turnkey sets it up with an LS1 intake, mostly because it's a throttle cable setup.

...with soft lines installed.

For those of you that are wondering, we put in the soft line sections in for future maintenance reasons. The body of the 80 is too tight to the trans for the fittings to be removed in place. If the transmission is ever pulled in the future, you can disconnect the soft lines without having to pull the entire transmission cooler line assembly.

very clean build! likes that

Most of the fasteners at the back of the heads are M10, and all the terminals for grounding the harness come as M8. We changed this M8 bolt to a stud to keep from having to hack up the harness.

The soft lines are a great idea!

Do the lines get flared and fittings for the soft sections? If not, what type of hose is that?

That looks so clean!
Is there a cheaper method with less fittings?

It's a Parker low pressure hydraulic hose, and no, the lines are not flared. The hose doesn't stretch enough to allow for the use of a flare on the tubing. We've found we can flare and put it on, but then you have to cut it if you want it to come back off. It would be nice to have the flared factory look, but then we'd have to use a softer hose.

There is always going to be a cheaper method than the way we do things, but we want everything to look and function as close to factory as possible. We know we got the details right when people don't even notice them.

The fuel rail on the Turnkey LQ9 is set up for -6AN, which is roughly 3/8". The stock 80 supply line is 5/16" and the stock return is 1/4"(or rather their metric equivalents). Since this engine would have a 3/8" supply and 5/16" return in most applications, we'll be using the stock 80 supply as a return and running new 3/8" for supply.

Here's the new 3/8" line all bent up with mounting tabs:

...a few installation shots:

Will this build be getting a larger gas tank or an extended tank addition?

This truck actually already has dual tanks. The rear auxiliary tank is a 45gal unit.

Here is a side by side comparison of the old vs new supply lines:

awesome work. keep it coming.

 

[rockrod]

looking mighty fine! i like the touches on the cooler line routing and the hard lines.
