85 burb meets 6.0 lq4

[low man]

im anxious to see how it looks instaled,maybe ill do the same to my truck.i have a budy who put one in his mud runner and it was a lot meaner than his old big block.took him a couple of nights to do.he told me that the flywheel of a 5.3 bolts on to the block and the torque of a th 350.he used the edlbrock intake and msd for the coils

[85burb]

I cant wait to see it installed too... I know for sure it will be 10 times meaner then my old sbc.

[WOOS1]

I am anxious to see you get this thing running! I really enjoy reading your updates. I really want to swap a 6.0L that I have into a 1990 K5. I am half scared that a built 700R4/4L60E will not hold up with the 33" tires I want to run. But looks to be a definate pain to find the right parts and install a 4L80E in the short K5. Do you think the built Monster you have will hold up long term? Will you be wheeling or towing with your suburban?

[85burb]

I do plan on some wheeling but not towing anything. I do think that the monster transmission will hold up. It has almost every upgrade they make for the 700. Says its rated for 500 hp and 450 tq. I still have 2 years left on warrinty so i guess we will find out. May not hold up forever but i am not worried about it. It will deff spin a tire befor it trys to break a shaft or someting like that. Hope to be finding out soon.....

The adaptation is not in the flexplate. The factory used a spacer bolted to the back of the flexplate on the crank hub to adapt the 4L80E torque converter to the 6.0 engine. It can be used to mate an older trans / torque converter to any of the LS engines. Runs about $35 from GM if I remember right.

There is also a kit from GM that has the flexplate and the adapter. Part number 12621399 and sells for under $50.

If you have a 99 or 2000 vintage 6.0 you will not need the spacer as the crank is thicker to make up the difference and will stick out of the block like the last picture. The 2001-up 6.0's the crank flange is flush with the block face.

looks like what I bought from Pace. Wouldn't fit my 200-4r converter

[LEEVON]

Ummm, wow! I paid $45 for those six bolts alone at a dealership.

[85burb]

So what is everyone doing for the coolant temp sensor and oil psi sensors? And where can a person find one of them block off plates that go on the oil pan to remove the oil cooler.

[68GMCCustom]

I'm planning on using adapters to put my old mechanical sensors in. Holding off on instrument upgrades until later...

The cheap and easy route is to tap the passenger side cylinder head for a standard 3/8-NPT fitting so you don't have to run a metric adapter for the coolant temp gauge.

There is a small bolted on fitting above the oil filter that people are tapping for an oil pressure gauge fitting. On the Vette it is tapped but some others it is not. I know the fitting is on the LS1's but don't know if it is on the LQ motors.

[68GMCCustom]

unless I'm mistaken (and it wouldn't be the first time) my motors oil sensor is in the top of the valley pan, at the rear of the motor?

on my genIV....I think the oil pressure sensor is in valley cover, crank sensor is on side of block near the starter, cam sensor is on the timing cover, and I'm guessing coolant temp sensor off the front of the drivers side head.

I do beleve you are right on all the sensor locations.

[85burb]

I found all the addapters i need on s&p. I hope to get my gasket set in this week and my timing chain also. Hope to get to put it togther for the last time soon.

[85burb]

YAY my gasket set and timing chain got in today. Now i have to find oil pump gaskets and i can install everything ecept my push rods wich i have money for in my pocket right now. All i need is new engine mounts, hoses, plugs and wires, map sensor, pushrods, oil and filter, sensor addapters and i think that is it. Then the on only thing will be time and place to install. Very excited!!!!

[85burb]

Almost forgot pic in all the excitment.......

[GasBurner]

[85burb]

Stupid question here..Does the oil pump have gaskets???? Or just the oring for the pick up tube??

[85burb]

They only have one...got it from gm today.

[85burb]

Got oil pan painted today. I have everything but the pushrods to put it together. Just have to paint the block and put it all back together. Then save up for the rest of the stuff i need. YAY

[85burb]

Just put in an order with SDPC for a set of Manley Performance 5/16 4130 chrome moly pushrods in 7.400 length. And a Balacner bolt from them. Looks like a renamed arp. It is there house brand.

[85burb]

The spark plug wires that fit a camaro should fit a LQ4 right?
http://www.summitracing.com/parts/MS...RO&prefilter=1 This is the set i was looking at.

[68GMCCustom]

the "truck coils" are different then the LS1 coils. Not sure if it would make a difference in the wire length tho?

[85burb]

wounder if it is just the coil shape to fit under covers or the connector shape. Hmmmm... Maybe i will just go to the parts store and compare. My engine only came with 4 plug wires. What kind of plugs do these engines need. Do they come with the fancy iradiam ones?

[68GMCCustom]

I'll try to take a look at mine and tell you whats in it. Its factory new so has the latest and greatest plugs they were using in 12/08.

My 03 calls for iridium plugs.
