Engine compartment done
 

I fired up my Gen IV 5.3 last weekend for the first time but I had to cobble together the air intake temporarily. Today the mailman brought me a 4" elbow that had long enough legs to allow me to clear the alternator. I heard the MAF likes a straight run so I centered it. My plan was always to have the top rad hose on the passenger side and the air intake to the drivers side, partly to obstruct the ECM and the associated mess of wires. I also made a block off for the big hole in the front ps of the engine cover and painted the cover with black vinyl paint to brighten it up. No deluxe heater makes for a cleaner look as well.

Very nice moe...

Looks nice and clean!

What kind of radiator did you go with? Inlet/outlet sizes? Upper and lower hose part #'s?

Re: Engine compartment done
 

Where’d you get your intake?

looks moe bettah than factory

Looks great! I'm with MDPotter. I'd like to know info on your radiator, inlet/outlet sizes and hose PN's. I'm at a point where I'm trying to figure out radiator hoses for my K10 5.3L Gen III swap. Any info is greatly appreciated.

The motor is all stock 08 Tahoe 5.3.

The radiator is an RND Fabrication downflow. I told him it was for an LS swap and I wanted the upper on the ps and a steam hose fitting.

Upper rad hose is Gates 21970 that I had to shorten 3 1/2". 1 1/2" rad x 1 1/4" engine
Lower rad hose is Continental 61416

My motor is Gen IV. Not sure if that makes a difference for the hoses.

I should add that someone on here used a Continental 64143 for a top hose but for my Gen IV it was too short and too small at one end. Fits Gen III maybe?

Oh you mean the air intake? I just cobbled it together using an elbow, some 4" tube and a 4" filter I bought on Ebay. I had to hunt a bit to find an elbow long enough so it would clear the alternator. The Maf is stock. It's actually a bit smaller than 4". One end I was able to hose clamp down, but the other end was even smaller so I cut a plastic strip and wrapped and glued it around to bring up the diameter.

I'm late to this but looks great Moe! Curious to know if you always planned to mount your ECM where it is. I've got a stock harness as well and have the same engine cover (L96) but want to route my harness and ecm either to back firewall or against the firewall in the cab.

Re: Engine compartment done
 

I had the stock harness thinned out but that’s the stock routing direction so I didn’t have much choice where the ECM mounted. The air filter hides it a bit. It would take a lot of work to re route a stock harness to move the ECM location but you can buy aftermarket ones that will work for what you want.
Did you notice the block off I made for the front ps of the engine cover?
