So you got an LQ9, not an LQ4?

Honestly, the tops are probably worth about $100 complete maybe $150. They are plentiful.

Heads are the 317 aluminum series. Why sell them? Same on LQ4 & LQ9 engines. LQ9 is higher compression with better rods, 345 HP stock. LQ4 has dished pistons, 300 HP.

Carb'd setup with cam should be a solid 400HP motor.

I wouldn't paint it anything other than the factory color unless it was a charcoal or medium grey. I am sick to death of seeing Chevy Orange, Red and Blue motors!

I am getting rid of the 317's and going with a set of L92's. They are some crazy cool stock heads, and I should be able to push more than 400 horse with them. Now you say I have an LQ9, is that because of the vehicle it was in?

Oh and it will be silver, there is a good reason why people don't like yellow/blue/red/orange, it *usually* looks bad. None of those colors would go well with my truck, unless I could exactly match the red to the rest of the paint. A silver and black engine bay will look very classy

If it's out of a '02 Yukon then it's an LQ4. Some LQ4's were rated at 325hp (like my old '01 Sierra C3). With L92 heads, MSD ignition, and a good carb setup you should be getting around 400hp...add a bigger cam and you should be over that.

[LuckyHenriksen]

I pulled the heads today.... are my pistons/cylinders supposed to have this layer of filth on them? Got some action pics of me doing some work to prove to my teachers that I actually did it haha.

[68GMCCustom]

lots of carbon build up...thats all. Use your shop vac and vaccum that stuff out of the cylinders as best you can, then maybe blow the remainder out...unless someone else has a better idea?


look at those heads though....the top of the heads and the springs are nice and clean...and sludge free.

According to this picture, it is an LQ4.

[LuckyHenriksen]

Haha that is my buddies GTI. It's cool, all I drive is old trucks....... and a GLI. Ok Im glad its just carbon buildup. I will be using the shop vac soon.

[LuckyHenriksen]

Anyone know how to get the fan/clutch off?

[texanidiot25]

Is it one big ass nut? If so, it's probably a left hand threaded nut, lefty tighty righty loosey... Bet that's been blowing your mind

[MrBeast]

Cool score man. I just nabbed me a Cummins today, so I am fixing to be neck deep in a swap too.

I like the direction you are going with the truck, it seems to me for your age you have your poop in a group.

You know when I was in high school back in the *gasp* 90's I would have killed to get a LS1 in my truck. You are awful damn lucky. I think this truck is going to wind up being Sick.

One piece of advice though, never sell it, Id give about anything to have my old truck back. I miss it like crazy.

As far as the fan goes, I am not sure on a LS1, but many in that era had just a nut that was threaded the opposite rotation of the fan, just have to follow the belt path and find out which direction it spins, and the fan will probably spin off the opposite.

[LuckyHenriksen]

Theres nothing on the front as far as a nut, I will go take some pics to convey what I am trying to say.... thanks for the support guys.

[LuckyHenriksen]

EDIT: My juvenile friend got on here while I was in the garage and posted .......

[LuckyHenriksen]

Here are the pics of the fan







I already got the plastic fan off, but the front clutch or whatever that is won't move


on a side note, anyone know a good way to make the oil fill in the valve cover not look so lame?

[MrBeast]

It is the type I thought it was, you need a wrench big enough to fit on the hex head of that shaft. It will turn off the opposite way the fan rotates. The whole shaft is the nut.

You will want to use a strap wrench to hold the pulley from spinning. If you don't have one you can take an old serpentine belt and put it in a pair of vice grips after you cut it down.

My S-10 had the same fan, what a ***** to get off! I put an electric fan in my truck to get some HP back. I cut the crap out of my knuckles when the nut finally broke free. On my S-10, when facing the front of the engine, the nut turned counterclockwise, but I don't know if the V-8's are the same or not.

Carbon build-up is common in the newer engines (for ALL makes). It's a good idea to run a cleaner through them once a year or so like sea foam and use a fuel injection cleaner fairly often.

Keep it up man, lookin' good

[LuckyHenriksen]

Thats a big mother wrench. Thanks for the advice

[mike nutt]

lucky ,
on you oil fill tube , there are some breather type fill cap that fit into the valve cover or you can remove the tube and screw the factory cap right into the valve cover , but you may have to trim your coil mount bracket slightly. there are several breather type caps on EBAY. well , good luck on your build .

Nice job holding out for that price. You ever need a hand out there let me know. My Hot Rod is always looking for a reason to cruze.

[71swb4x4]

The fan comes off fairly easily with a big wrench and a special tool that keeps the fan from turning. Here the local Advance Auto will let you use the tool. You pay for the tool, then return it for a refund. A BFH helps too.

That's actually what I used, it was about $55 to rent it, but you get it all back.

[texanidiot25]

If your looking at the front of the engine, your going to turn it clock wise to loosen it. The exact opposite of Lefty loose righty tighty.

[LuckyHenriksen]

Cool guys, thanks for the answers. I will work on that fan tomorrow, and see if I can get anywhere with it. C10 KID, thanks for the offer, you never know when I could use an extra hand.

[thirdstreettito]

Paint the fan red. It'll look good.
