So It's begun... 5.3 swap coming soon!

Small update for any who care, project is currently on hold as my brothers turbo IS300 decided to throw a rod and I had to lend him my DD while he's getting a new block... hopefully we'll have that car back together next weekend so I can pull the motor and start fabbing up some mounts for the 5.3, Also interesting fact about the 5.3 that I just found out today at the engine shop. Some of the 5.3's with a certain casting of the heads leak a small amount of coolant into the block. Most people think its a head gasket leak but certainly this plagues many of the 5.3's so I'll be checking the heads for the casting and see if mine are plagued, hopefully not!

Can say I never heard about the casting leaking. But the intake gaskets on just about all vortechs (3.1, 3.8, 4.8, 5.3, 5.7,liters) have had the problem of leaking coolant into the block and externally. From the one's I have saw it was always around the stud in the left rear of the intake.(driver side) but not limited to that area. Always a good ideal to change them out as long as you got the motor out. The 5.7 in my truck and my friends truck both went between 100,000 and 110,000 miles. The 3.8 in my nephews Pontiac went at 90,000 miles. I know of a few more too all right around 100,000 miles

Just a small update, still waiting to get my Daily back so I can yank this motor/trans out... Picking up a Dana 300 transfer case and ordering an adapter kit for the 4l60e to mate to it... everything else should be pretty much a fabrication job. Hope to get this running before summer or early summer. Will definitely be losing the T.O.D. but I don't think the tcase would actually be able to handle the power even if mated up to the trans.

I'll be watching this with some interest!

good luck, cant wait to se what happens!

Thanks for the interest.. once I get all the parts and actually start doing work I will start a build thread. If anyone knows of anyone needing a stock motor/trans/tcase please let me know. Selling this stuff will expedite the process :)

Will you be able to keep the a/c with this swap? I know others in the past have had issues finding a place to fit it.

I don't think I will be able to, if there is any room for it I'll be amazed.

So which year is the silverado you bought this engine from ?

According to wikipedia GM's 5.3L build back in 1999 was rated @ 270HP and 315lb of torque.

Then in 2000 GM upgrade the engine to make it kick out 285hp and 325lb of torque 'till 2003.

In 2004 GM make it up to 295hp and 335lb of torque.

I guess the one you gonna use is from a '99 silverado isn't ?

The motor I picked up is out of a 2004 Silverado, so the 295/335 motor...

Small update?

Awesome, I'm so excited to see how it goes!

The 5.3l I put in mine was from a 2009 h3 and I did go with the dana 300. I believe the motor is a little smaller than the 5.3 your putting in.

I'm really curious... Why hasn't anyone gone larger than 5.3? 5.7 and 6.0 have the same size blocks.
Is it the cost?
