How To Tell The Difference Between 5.3 And 6.0 Vortec

Differences betwixt 4.8L, 5.3L and half-dozen.0L
I know that pretty much whatever modernistic from the four.8 will fit the 5.iii wil fit the half-dozen.0 and all combonations, but what are the different internal components that stop a person with a iv.8 from simply boring and stroking (whatever is neccessary) to obtain the 5.3 or 6.0.
My question sparks from seeing enough of people swapping out the four.8/five.3 to the 6.0 and I figured if a simple rebuild with bore and stroke were possible somebody would already be doing it.
If this question has already been answered I'1000 sorry, I searched just couldn't really notice anything.

The engine block bore is the aforementioned for the 4.viii/5.3 simply the crank and rods are different, shorter stroke. The 6.0L has two configurations, low pinch LQ4 and high compression full floating pistons in the LQ9. The four.eight/5.3 engine doesnt take enough wall thickness to handle existence bored out to 6.0 without being sleeved. By that time its cheaper to buy an LSx cake. I haven't heard of anyone putting a four.eight creepo into a 6.0 block to make a loftier reving engine.

it merely makes sense to destroke an engine if yous accept to meet class deportation limits.
- How does the vi.0L compensate for the thickness without going to a new block. I don't know also much about engines merely information technology seems the only way to take thicker walls is to space the pistons farther apart. Which would mean a slightly longer block and probably a unlike crank and camshaft as well....

they cast a larger diameter into the piston liner area on the 6.0. The 6.0 cake is a unlike cake than a 4.8/5.three block. The 6.0 cake can be bored out +.030" larger to make information technology a iv.030" diameter, besides. The 4.8/5.3L block tin can be bored out to fit an LS1 piston upwards to 3.905" diameter making it a 5.7L if you have that done.

a longer block is non needed. It could help, and I could see information technology happening in the future (like the NASCAR R07) but that is unlikely.
The old 400 block and the LS7 each had a four.125" bore. The Quondam 267 SBC had a three.5" bore. THey all share the aforementioned bore eye to bore eye distance of four.400 inches. It is possible to get a bore upwards to 4.200" only things get hairy effectually at that place.
- I've actually heard that a 6.0L block can exist taken as far as .080" over, but I've never seen it.
The 6.0 cake can be bored out +.030" larger to make it a 4.030" diameter, likewise.
The four.8/5.three block bored to accept an LS1 piston and with a four.00" stroker crank will make a 383...not too shabby for a cake you can pick up for $100 or and then.
