ITS 325 CUBIC INCHES. Do the conversion or easier yet, go to www.Chevrolet.com and look for yourself under the 5.3l engine specs. A 350 small block is actually the engine found in earlier model chevrolets and is 5.7liters.

Perhaps a little confusing for the newbies, but the capacity measured in litres (in SI units) does not always convert linearly with the stated block size, measured in cubic inches (in imperial units) because the bore size may be different. For factory vehicles, the stated capacity (in SI) is usually over stated (actual measure is in CC). The manufacturer tends to round this up, though the bore size may not match this exactly. For example, a vehicle which is stated as a 202 cubic inch or 3.3 L engine, or 3300cc is not a true conversion. 202 cubic inches converts to 3,310.19 cubic centimeters. So in this case, 3.3 L is understating the true capacity. Try www.easysurf.cc

That's www.easysurf.cc/cnver6.htm#ic2 for the conversion. Baring in mind that the stated cubic inches is also rounded.

i was a GMC technician for a little while and everywhere in the dealer books they said it was a 327CI

conversion and math wise it's a 325.2 but in actuality it's a 327. but if you want to ask for parts it's a 5.3L. Don't get it twisted or the parts guy will look at you like a dog listening to a whisle! lol

Okay...I am a technician at a GM dealership, I went to the GM/ASEP program at Oklahoma State University-Okmulgee, and i'm ASE certified...the actual cubic inches for the 5.3 is 325ci...the reason everyone says its a 327 is because early model vehicles that had the real 327 in them were designated as 5.3 liters too...GM labels it as a 327 in all their books and advertising because thats the engine that they use to make that everyone is familiar with...even our teachers at the GM training center in Dallas say its a 325...

The correct answer is 325 cubic inches... All tho it is a common misconception for people to think that it is a 327, becuase that was a popular motor for GM a while back and it has a good namesake so GM actually calls it. that

All the gen 4 5.3liters are 325 c.i. If it has the iron block it's an LY5 Aluminum block LH6 Either way same displacement... (pi*(bore/2)^2)*stroke*(# of cylinders)=displacement 9.601 cm bore 9.2 cm stroke => 5328.45cc motor or 5.32845L 1 liters = 61.01 c.i. 5.32845*61.01=325.089 ci rounded to nearest integer, 325 c.i. If you want a complete run down on the engine SAE sells a nice bit of literature on it... if you want to shell out the money... http://www.sae.org/technical/standards/CPGM2_07LH6_LC9 --------------------------

326.54 this is the total micrometer reading when multiplied by 8, depends on weather you are reading the bore or the piston circumference x8. I think there are two correct answers. I presume the piston is actually slightly less. An engineer may be measuring what goes into the void, not the void itself. I'm going to call rounding up to 327 as most accurate.

Chevy used to have a 327 which was the 5.4L engine. Now they call it the 5.3L engine so it is the old 327 down sized slightly to a 323.

it isnt a old small block chevy at all. Its the LS series of engine that has nothing in common with the old v8's pre 99ish

deed BMW Have. 5.3 l what is it and how much hp

324.991 to be exact. Sorry...

Who really cares! It's a 5.3L as advertised!

You see folks, 325 is what gays say. 327 is what real men say

The gm 5.3 is a 325. It has nothing to do with the old 327. They didn't bring it back. However that may have been a good play for them as ford it doing the "5.0" yet again. But 5.3l is converted to 323.429 cubic inches. It's not a matter of manhood. There are the facts. I'm sure there is a decimal after 325 ci but I don't care to figure it out...

Interesting to know about the new way of recognizing engines in liters to the old way cubic inches, lot of bulls#&t to remember.

Just let's us old timers know what to expect from the engine in the way of performance. If we owned an older chevy 327, the 5.3 will perform the same.
