5.3L to a 6.0L

[uncleiceberg]

Ok, so i may not be as seasoned a mechanic as many of the members on our site but i have a question regarding the 6.0L swap.

Is it basically a kit(pistons, gaskets,etc.) that is installed, well built, that converts the 5.3L to a 6.0L beast?

 

[vatahoelt]

no, people buy a 6.0 motor and replace their 5.3 motor

oh, i went on ebay to do some searchin and only found these kits.

where about could i start looking to find a replacement motor??

BTW, thanks for clearing that up

Sometimes you can find them on craigslist. Seems like its usually a gamble on if their in good shape or not.

you know what a longblock is, correct? Basically, all you are doing is swapping everything, from the heads down...the intake and fuel injection comes off, with all accessories and bolts to the 6.0 longblock. It's all the same externally. Look for 2004 and up 6.0's, they can be either LQ4, or LQ9's.

Hmm, so the 6.0 gets the extra displacement and power from the heads? The crank and pistons are the same size?

checkout car-part.com thats how i found my motor...

the 6.0 is a completely different block from the 4.8/5.3 which is the same..it has bigger pistons etc...the cam and crank are the same i believe, but heads, pistons etc are different...

internally different, externally the same.

4.8 , 5.3 , 5.7 LS1 , 6.0 are all Gen III Small blocks.

They all can share camshafts, heads, intakemanifolds, exhaust, and accessories ( alt, power steering ect.)

But they all have different bore sizes to get their cubic inches ( or litres)

The LS1 has an aluminum block.

The others are usually Cast iron blocks, but there are all aluminun 5.3's out there.

You can put a nice cam and valve springs in a 5.3 and get over 400 horses.

Hope this helps.

I think 5.3's are underappreciated, They are great engines and can be had inexpensivley. They run sooo much better than the older 350's.
