1)What year did Chevy come out with the v8, 8.1L engine (2500)?
2)Is this the version of the 454 (8.1L)?
3)What is the 5.3L, 6.0L & 6.6L?

I know that someone out there knows the answer:help:

it's late and i can't use the brain to figure the exact cubic inchesbut here is a close guess. 8.1 liter= 502, 5.3 = 327, 6.0 = 366, 6.6 = 400, someone correct me if i am wrong:confuzeld

1 Litre = 61.02 cubic inches (CI).
Just Shawn is close enough on his numbers. The 8.1L was introduced in 2001 along with the Duramax. The 8.1L was an updated version of the 7.4L (454).

The 4.8 , 5.3 , 6.0 came out in '99 with the new body style trucks; 8.1 and 6.6 diesel were a few years later (as posted above).

The new body style truck started in '99 (actually late '98) BUT the old body style (started in '87) ran up to 2000 year model. Two totally different trucks were available at the same time for a few years.

I was sure the 8.1 is a 496 CI and the 5.3 is 325.

let's not confuse the old 327 chevy... that was 4' bore 3.25 stroke
FYI the 350 is 3.5" stroke and 302 is 3".

justshawn is close here are the figues that I came up with:1.) The 8.1 came out in 2001 when the new style HD's came out2.) The 454 (7.4) is similar in design but different in dimensions3.) 5.3 is approx 325 cubic inches, 6.0 is approx 364 cubic inches, and the 6.6 is approx 400 cubic inches
sorry for bunching all my words together I don't know why my computer is doing that, I tried editing but it didn't work

Actually, the Old Faithful 5.7 was ( bore x stroke ) 4.00 x 3.48.

4.8L = 280, 5.3L = 325ci, 6.0L = 364ci, 8.1L = 496ci, all gassers. 6.6L TD = 403ci

Not much of anything is interchangeable between the mark series (366,396,402,427,454) and the new gen 8.1 except for the physical mounting points(bellhousing,motor mounts). Oil pump is driven by crank snout, oil cooler fittings integral in block, no distributor and associated oil pump drive. No throttle cable. IIRC about the only interchangeable parts are the exhaust manifolds.
I believe intakes are offered to put carb on 8.1 and some stand alone DIS systems.

first off the 302 is a ford motor, secondly the 8.1 is a 502 and the 5.3 is a 327. the 8.1 is a beefed up 454, more horse power and torque, it was introduced in 01 with the duramax, and the 4.8, 5.3 and 6.0 were available in 99 with the body style change. the 8.1's will pass everything on the road but a gas station, awesome motor if your looking for hp, but with gas prices, your better off with a 6.6, in the long run you will come out ahead

secondly the 8.1 is a 502 and the 5.3 is a 327.

Sorry, no offence...but no its not. The 8.1 is a 496ci, I will bet you my truck and 100 million dollars. The current Vortec 5300 is a 325.xx but so close that most people call it a 327. Chevy.com seems to agree with me too...

and the Dmax is a 402, its stamped on the engine identification tag attached to the side of the engine IIRC...

:nono:

302 was also a Chevy motor back in the late 60s.

2 observations from Ben's attachments:

GM was ripping people off with the 5.3 over the 4.8. $900 more for 10HP and 40TQ. :wtf:
The new 6.0 vortec max -- same motor but with a bump of .7 compression. What was the diff in HP/TQ numbers?

um, dude you realize there was a 302 in camaro's right. have you ever heard
of a dz 302?

first off the 302 is a ford motor, secondly the 8.1 is a 502 and the 5.3 is a 327. the 8.1 is a beefed up 454,


Thanks I needed a good laugh!!!!:lol: :funnypost :exactly:

Ithought Ford used the 302 and GM used the 305.... both to race in the Trans Am series.

Ford did have the 302, as did GM. The GM 302 is pretty rare but it was one heck of a motor back it its day. The 302 was a nice high revving motor, I don't know why they didn't produce more of them, maybe someone on here knows more about that.

Hear I thought that we finely dismissed the myth that a 8.1l is a 502. 8.1l is a 496, 502, 8.2l. My .030 over 496 is a 503 or 8.2l. There is very little in common between the a 454 and 496. :p:

Yes I think most people know that the 8.1 is a 496. Some people get it confused with the 502 BB because of the similar size/ cubic inches. As far as the 454 comment, I was simply trying to state that they are both BB GM motors with lots of torque, wasn't trying to get all technical. Sorry to get so Off Topic.

4.8L = 280, 5.3L = 325ci, 6.0L = 364ci, 8.1L = 496ci, all gassers. 6.6L TD = 403ci

Hey,

Like others have said, google a 1968 Camaro Z28 ( 302 V8 ) you will get some hits.

The High revving 302 was a destroked 327. ( that was what I was told once anyway!! )

DZ = 327 with a 283 crank = 302! a hi rev hottie! I almost built one over my 327. I had a steel 327 crank that I could just toss out! Mine is like 330 bored .30 over.

365HP normally aspirated full floating forged .100 domed pistons camel humped 202 valves 164 chamber heads, performer RPM manafold...

:ro)

302 has 4" bore 3" stroke. Made so the Camaro could run the Trans Am series where the max was 302 C.I.
If you think you've found one in a camaro the most common block code id is DZ, some were MO, DZ regarded as being the better of the 2.
Drove one once, had 4.10 gears, what a blast.... until the road gets wet, then forget about taking off in a straight line... not a whole lot of bottom end power but came on strong above 3500
edit: About forgot... car had factory chambered exhaust, dealer added accessory, man that thing had a mean a$$ cackle to it

Lucky man, I whish I got my hands on one! my next chice would be a 427 Yenko.

I think the 8100 is a 496. Also, much of the diesel attraction is being lost with the high initial cost and the high cost of diesel fuel. In my area, diesel runs .75+ more per gallon than gas. I got 14.1 mpg out of my last tank of gas on my '06 8100 w/the 6 spd Ally. Granted it was all hwy. The DMax will get about 19mpg? I personally could not justify the $6K cost of the LBZ for a 5 mpg difference. I would never recover the initail cost. Aside from the CDI factor, I dunno how it can be justified unless you haul very heavy loads the majority of the time. Don't get me wrong, I'm not bashing here, just doing the numbers. Please show me where I'm wrong here.

I'06 8100 w/the 6 spd Ally.

Off topic but...

This is a HUGE favor to ask...and dont worry about it if its too much trouble...but do you think you could read me the part number of your 2006 8.1 ECM and TCM? Its for a project we're working on...seeing if the new 4th gen 32bit TCM will communicate with the old 16bit Dmax ECM. If the 2006 8.1 ECM's are the same as the previous 8.1 ECM's, than there was no change and a 6-speed TCM will be able to communicate with an older style ECM, which is GOOD NEWS...

Be glad to. Just tell me where to look. The truck is out getting a spray in bed liner, but I'm sure I could do it by the end of the week.

I think I read somewhere that the GM 4.8 is a 292 c.i. I'm pretty sure about that.


The Ford 4.6 is a 281.

The ford 4.6 is a joke IMO

I had a little black Mustang with a 4.6 that would toast your weenie.):h N/A:eek:
mike

It is one of the most durable engines I have ever driven. I mean it can take a whoopin for several hundred thousand miles and "get you home". It is however, alot of bark and not much bite. Maybe I'm just used to a 2 ton car with a 250 h.p. 4.6 in it. I have however flat out, outran a GT that was modded. Walked away from 75 on till 130. No replacement for displacement. And torque won the day.

And this will give what you are looking for.

I sure am glad we are not trying to figure out the displacemnet on rotarys. No one can ever agree how to calculate them.

Man, I still miss my old 99 4.6 Interceptor; only 281 cubes but it would really move that car.


These are the Cubic Inch Displacements as claimed by GM:

4300 V6............262 cid

4800 V8............293 cid

5300 V8............325 cid

5700 V8............350 cid

6000 V8............364 cid

8100 V8............496 cid

Duramax............402 cid

4.8L = 280, 5.3L = 325ci, 6.0L = 364ci, 8.1L = 496ci, all gassers. 6.6L TD = 403ci

4.8L = 294ci

Ford 4.6= excellent low end torque, no midrange anything and no top end pulling power. Interceptors have an excellent put you back in your seat shift but all bark and not much bite. It is durable though.

5700 V8............350 cid

not to burst your bubble, but the 5.7 is actually 348.9 cid...;)

Welcome to the forum. Try not to resurrect old forums and go ahead and read the rules. Enjoy, its alot of fun in here.

302=67,68,69 Z-28 only,4spd 12 bolt only. 8.1=496,new gm truck motor.502= crate motor only.Hope that helped.302 was a fun motor from 3800-7800 rpm,I sure miss that sound!

not to burst your bubble, but the 5.7 is actually 348.9 cid...;)

Ls1 5.7L is a 346 cid.:p:

Off topic but..... seen a lot of 4.6 dorfs burning mucho amounts of oil with less than 80k on engine, that's why I say it's a joke

well, thats an LS1, and they called it a 5.7 for marketing reasons

about the 302, i have two blocks and a set of heads if anyone wants them? j/k, sorry. my dad used one block in his ModelA, he said with just a cam, new vavle springs, pistons and rods, he had it up to 9200rpm down the track thanks to 6.20 grears.

I just learned this yesterday. My 00 was 3 quarts low. 97,000 miles.

[useless post]

the first year V8 for Chevy was 1955 (production, that is). It was a 265ci engine.... first of the Gen-1 small blocks.;)
