I'm looking to buy a 95 Sierra 4X4 with the above engine. However it looks
just like a 307 that I had in a 72 malibu. Is GM still using that same
engine? What have they done to modernize it? I can't believe that it's not
fuel injected! I'm replacing an 87 Ranger with a 2.3L which appears much
more modern than the 95 Sierra engine. No wonder GM is having financial
problems. Comments please. TIA
The 5.7 is a 350 c.i.
It is TB fuel injection...and is basically the same small block that you had
in your 72, and your 72 had basically the same small block that were in the
50's Chevrolet V8's.
What's wrong with sticking with what works?
No wonder GM is having financial problems? Now I'm sorry I even attempted to
answer your question...
I agree with Advocate, the chevy 350 is a masterful engine. It has not
needed to change. In my opinion it was one of the worst things they
could do was stop the production of the 350 in favor of the 5.3 and
6.0l engines. What I believe is causing the problems is the fact that
the auto makers want 35 40 thouseand dollars for trucks, and cars. The
economy thing is still going strong but gm is not going with the flow.
And the autoworkers have done a wonderful job of demanding to much
money for their services. They simply made gm go over seas due to the
cost of keeping the workers going. just my $.02
For My .02:
Product will not sell for any less whether built overseas or North America.
The real issue is reliability (sound engineering) vs gimmicks which could
have used less of. Less money spent on gimmicks would freed up resources to
really FIX what needed fixing. Discounting for market share and with added
gimmicks are what ails GM.
Imports are not fancy, are fairly well built and run reliably to boot.
To save money, cutting gimmicks would seem to me, a place to start the
turnaround don't ya all think?
If gasoline was still under $1.00 per gallon, nothing would be wrong.
Jeeez, don't take it personally....
Maybe a little more clarification for my post would help.
I'm looking to replace my Ranger. I want to buy a boat and the Ranger isn't
big enough to trailer it. So, I started looking for a bigger truck. This
Sierra looked promising even though it has 155,000 miles on it. But, I was
suprised to see this engine when I popped the hood. Initially, I thought
that the engine must have been replaced because....well, it just looked so
old. Admittedly, I've been away from GM for some years and wasn't aware of
the state of technology in this vehicle. Sorry if I offended you, but it
seems that a lot of other people (investors) aren't too pleased with
GM.....Not to mention the thousands that are going to lose their jobs.
I didn't take anything you said personally. You made a stupid statement in
your first post, that's all. If one needs to explain to you why General
Motors offered the small block basically unchanged for nearly 50 years, you
really don't get it so the explanation falls on deaf ears.
I like GM pickups.
There is nothing wrong with the small block engine or design even today.
Any problem with one is due to quailty control, not design. It is quite
likley the best eninge of its type ever built even today.
the 5.7 (350) Chevy engine has always been a reasonably good
performer. If you ask me its only gotten better.
Like one of the other guys said I don't follow why GM needs three
versions of the small block in the pickup. I'm not even sure what
they are.... something like a 4.8, a 5.3, and a 6.0 ....

It has TBI (Throttle Body Injection) and there is nothing wrong with the
350 design. I was ahead of its time when it first came out and has no
design flaws that need improving. THe 350 was scrapped in 02 not because
it was bad but because they could build the modular 4.8/5.3/6.0 engine
cheaper. The old GM small block is a tuff act to beat.
Sure the 2.3 is more modern. The pinto didn't come out till the 70's.
Where as the Small Block Chevy First Debuted in 1955, with a
displacement of 265 CID.
Where as Chevy has made improvements to the block, and changed things
since 1955. Ford uses a pretty much unmodied Pinto Block, with a 1989
and up cylinder head. The reason your 2.3 has 8 spark plugs is, ford
could not get the engines to run clean enough. So their solution was to
add another 4 spark plugs to get a more compleate burn.
As for a 86 UP 350 being the same as a 307, it's a far stronger engine.
307's 262 V8's, 70's 265 V8's are the weakest SBC's ever made.
The GM 5.7 (350) is NOT the same as your old chevelle 350`s...In 1986 GM
made a 2nd generation 5.7..which is externally balanced (like the 400 sbc
and the 454 bbc) also the valve covers are held down by center mounted hold
down bolts compared to the 1/4" edge of valve cover mounted bolts...but all
in all still one hullava strong running motor,...Sid
