Well, truck motor blew up today and is dead

[OldCracker29]

The 4.3 is basically a 5.7 with two cylinders chopped off.
I have had several 4.3's.

Good luck.

Yep!

I'm on #2 in the Blazer

How do you tear up a 4.3???
I am on my 4th truck with a 4.3.

I have put a "TON" on miles on them and have had almost no trouble with them AT ALL.

The one that burned in my garage fire in November of 2006...(it was a 1999) ... had a "QUARTER MILLION MILES" on it.
Still didn't use any oil between changes and ran as good as the day I bought it new.

The 2006 I have now... that I bought in 2007 .... has over 80,000 on it.
All I have ever done to it is put gas in it... change the oil every once in a while... and drive the heck out of it.

Have you read any of his threads on how he literally abuses that thing?

It got a little thirsty in a river... Bent a valve... 15000 km later the valve dropped...

Maybe I should post up a couple pics in another thread

Yeah... I remember that.
I know what a dropped valve can do.

I popped the head off of a valve in a BB 427.
It busted the piston...bent the rod and the wrist pin messed up the cylinder wall too bad to be fixed.

Had to put a new crate motor in it.

it was rebuilt at 360 miles due to accident and never worked the same again, just my luck, worst f-ing time to happen..

it blew a hole thru the cylinder wall, it's fubar

Damn...real sorry to hear that.
Have you checked around at wrecking yards... see if they have a cheap one that you could just swap out real quick?

That would be the easiest and cheapest way to go.

But not warranteed.....just "hope" they work and I'm out $1200, But I found one from gearhead crate motors, $2200 shipped to my mechanics door, then $245 back when they pay to come get the old one. $1965 -ish

I'm still looking though...not giving up on these few from the salvage yards that are under 40,000 mile, under $1000 bucks.

just 2 of several....but not warrenteed, not like new/reman. crate, strictly get what you get and hope it runs for a day.

Dang that is a lot of money for a 4.3. Can't you just get a used shortblock somewhere and reuse all of your other stuff way cheaper than that?

 

[drperry]

That IS a lot of money for a 4.3

That better include everything...

 

[Ninja_Lawn_Guy]

he said it has gaskets and stuff too...I'm liking the upgrade mojo...but that comes with replacing a bunch of other stuff..I want the stuff I have to work so I guess I'm going exact replacement. 4.3L...like the $850 one, 33,000 miles from a silverado...I'd say exact swap, like turning back the clock on the engine I have. Hell he may have some stuff still hooked to it, make my job easier..
