Cold air intake

[AuroraGirl]

I turned a Silverado box sideways so the opening picked up the stock cold air hole through the radiator support. Used 4" mandrel bent pipe that I cut too short and added an inch back in then didn't grind it down enough lol. It's got a brace to the alternator mount bolt for support in the middle. Then some black paint. I went to the driver side because that's where the ebay harness had the maf wires routed. I still had to extend them a few inches. I used a stock high flow box based on another post where Keith had said they were designed for big blocks and diesels so it's overkill for the small blocks.

you have 2 issues

your tallest point in the cooling system is your radiator hose
I see little evidence of a coolant reservoir .. so heres some tid bits:

LS engines have a area in the heads that trap air/steam. This air/steam is vented to the cooling system via the steam lines. The steam line should be tied the cooling system.

If you T it to a heater hose it will be dead headed. The heater hose is not on the suction side of the WP

3 choices work - Radiator, WP suction side or Top radiator hose.

by having a radiator cap and no tank (that i can tell) you will need to do something with your vents. if you have an unpressurized reservoir, i think the same applies

Also your air duct hits the shroud. id clearance it or something because it will make noise with engine flexing and stuff.

Does anyone know where the best place to get 4wd drop spindles and Stock Leaf springs ?

What kinda truck are we talking about? There's no such thing for squarebody 4x4s cuz they're straight axle...

I have zero issues with that stuff

It's the stock radiator and overflow setup. I guess the hose is the highest point in the flowing system but the reservoir is highest overall. It may not be engineered correct but I can't make it run hot and the heater is a freakin furnace lol. So it seems the air has worked itself out and there's no pockets

I drilled and tapped the water pump for the steam vent. I've done several LS swaps this way with no problems yet. Same with the radiator. The last 2 pics are a 2wd truck I did

The air duct does not hit the shroud. Its actually closer to the alternator but can't hit it either because of the bracket holding it in place. The pic is deceptive. It was definitely a tight fit

This thing's been together for almost a year and had a few offroad excursions. I'm pretty happy with the initial setup

77 GMC Serria I figured that out. I am making my square body stock height so I am looking for stock leaf springs and then I will get stock tires and rims for it. I am swapping out my TH350 trans with a 4L60e and I am looking for a NP-208 Auto transfer case with a passenger side drop down.
