Looking great man!

Awesome job so far.

Thanks

When you welded the shock mounts on the axle did you do it with the assembly in it or not I ask because I was told one should never weld the rear diff with the guts inside of it due to the heat hurting the bearings and seals. I wish to do some welding on one in the future to change out the way GM designed the leaf spring attachments.

Yes left everything in. The shock mounts were far enough away if you weld one piece let it cool completely then the other side.

LOVE the little dollies!

They brought the lower control arms 1.5" above the floor. Didn't have to lift the body as high to clear.

Not much done. Spent about 10 hr figuring out a air cleaner and location.

Finishing up on the air cleaner assembly, still need the end piece. The hardest part was making sure I could get to everything I needed to without taking it off. Like oil dipsticks and brake reservoir and still shut the hood. I used a air filter from the Tahoe. Got lucky again the Tahoe elbow with temp sensor and air filter service indicator along with a silicon 90 worked perfect. I could have made it easier by using a K&N filter but I wont put that crap filter on anything. No I'm not concerned about not having cold air to it.

Now for oil fill, possible passenger side valve cover?

Nice work - fab stuff and all - we all hope your intake works out.
Not many that draw from that engine compartment do...

Thanks. The reason Im not worried is when I did the lift and had the 4.3. I used the stock air box but took the cold air duct of because no way would have fit. It sucked under hood air all summer and winter. No issues. Hope your not right this time.

Why do you think K&N filters are crap? just curious what you knw that I may not about them.

I've had them in the past and always had some light dust in the air box and hoses after the filter. I thought it was me not getting it set in just right. For 2 filters the same size and 1 flows more air it has to have larger space in the filter material to do that or more pleats. In this video the K&N does not have more pleats or is any larger than the rest. So it must have larger space and that can't trap small dirt particles.
I did look at a replacement K&N and its is smaller than paper filters. About 1.5 in height and 1/2" in diameter for normal duty filters. Heavy duty paper are 1.25" larger in diameter.

Looking good with the factory parts.

Moving along. Maybe get it started today. I want see if I need to fix anything up to this point before I button it up. Air cleaner housing is done except paint. Tahoe Rad hoses are in, only had to trim the upper. Need to finish up a little wiring for the fans. Exhaust is almost in but only to the mufflers. If it starts and runs then Start on the Transfer case wiring. I have it done just route it in the van and find a place for the switch.

Years ago I had a K&N filter in my K5 blazer but never tried one other then that to me I didn't see reason to spend the money. Thanks for the info Guys. Mark
