85 burb meets 6.0 lq4

[85burb]

Oh ya.......... forgot to mention i think i have bought a house with a 3 car shed/carport/barn thing. So i now (or soon) will have a good place to work on buddy. He is excited about all this. No more rain on his head (that is if it would ever rain here again) he says!

For got to post a pic of the coolest burb other then mine i have ever seen......

[85burb]

Well i got my burb back from rear end shop today.........I have failed myself. I told my brother 98 time befor he ordered his gear set to check the ratio..... So i should practice what i tell him sometime. As it turns out i hade 3.73 gears in my truck. The set i ordered are 410. The diff shop did not think to look at what set i had in it cause i got the parts my self. So it looks like i will be getting thr front done sooner then i had thought. FAIL!

Oops! Feel better with the new gears does it?

[85burb]

The guy that installed diff says to brive it nice for 2 heat cycles then get on it. I deffinitly feel a difference. The speedo is way off i think now. I bet i can do some really nice burnouts now, It did them really nice ones with the 373.

[85burb]

Here is a pic of the old worn out diff and gear. The fluid in it was a mix of 50/50 oil water. The last time i went threw water that deep was 3 years ago when i lived in colorado. The spider gears all had pits and chips and the thrust washers were also worn badly. The guy had to scrape rust off the inside of the housing and remove rust from wheel bearing area also. The gears were gm gears from 1985. I was told that the axles were from a 79 k20. They sure held up good no mater when they were made. I drove it prob over 10xxx miles with the fluid like that. The gears had a great ware pattern on them too. Just showes how tuff these old trucks are.

Ah the accidental upgrade, I love that! I bet those 4.10's will feel great with the way your rig is set up.

[85burb]

It deff feels different. I have on more heat cycle tell i will get on it. I am sure it will be faster. I am not sure if the gear change will help my speedo. Befor it said 55 and i was actually doing 65. That was with 373. Now it has 410 gear. Would that help my speedo or make it more off. I am thinking it would help right?

[68GMCCustom]

should make it closer....?

[85burb]

That is what i was thinking. But i am not sure. Will have to bust the good ole gps out and see.

Well i took buddy for his first long drive with new rearend. My speedo is exactly the same as my gps. It is dead on at 35-65. Befor and after the gps and speedo disagree a tad. It also drives way better the befor. Has more power runs smoother around town due to rpm be a little higher. 65 mph is a little under 1900 rpm. I love the new set up. It spins both tires if i "power break" or stall test or what ever you call it. Deff have some wheel hop now. But overall it is perfict.

Launch pretty hard if you just mash it?

Oh ya. Befor it would most of the time smoke a tire now i am worried about breaking a seat....

[85burb]

So the hole time i have had the new motor in the truck i have had a slight issue i have not messed with. Some times in or out of gear you can hear the fuel pump change it humm and then the motor bogs down to like 200 rpm. I am not sure if it did it with old motor but i dont think so. It will idle great then just bog down to 200 and come right back up to 750. It did it with efi and with carb. It has never died. I dont think it would be trans related cause it does it in gear and in N. Any ideas?

[68GMCCustom]

wow that's a tough one...since you changed the fuel system completely. I'm guessing it has a different line and fuel filter then before too? If so...the only constant is your gas tank. Any chance of contamination?

Any chance the MSD is causing it?

[85burb]

It is a different filter but same line. I have one of those see threw glass filters infornt of my pump and it is clean. I dont think my tank is contaminated. It has seen many many many gallons of fuel threw it and gotten faily low a few times with no change. It is like something is draging the alt down or something. Cause if it were fuel i dont think it would have affected the carb right at the same time the fuel pump starts to get loud. Cause of the resurve in the bowl. I can tell you exactly how far i can go on a float bowl full of fuel. I used to for get to turn my fuel pump on some times after sitting at work waiting for the gate to be opened.

[68GMCCustom]
