Is this realistic?

I have a bunch of LS1/LS6 parts sitting around and want to make a motor.

I have some early AFR LS1 heads, a new 110 LSA cam, 1 7/8" longtubes sitting around doing nothing.

I'm thinking doing a LS3 block + AFR heads + 25 pulse ECM + 4.25 stroke to end up with 440ci in a 03 Vette.

You'll be close to pulling the pistons out the bottom of the bores, it's pretty iffy with a 4.125" stroke in a stock block...

McRat

Thanks! I can get a smoking deal on a 4.25 crank, but perhaps it's too much.
It will be a "track only" engine, not street legal. Lifespan isn't a big deal, but blowing up in 10 minutes is.

McRat

Who's making the shortest stroker pistons?

lil john

this xbox ... 10 min 2 post something
1st crank is 2 big sleeve is 2 short
2nd reluctor 24x vs 58x signal
the biggest recommend crank is 4.100 for ls3 block but 4in. crank is best
if a builder tries 2 build this shop else where
Darton 5.9 sleeves are needed
I can get eagle all day long 4 $750.oo

McRat

Google won't translate that to Engrish.

I'm not sleeving ****. You want a shitty engine? Sleeve it.

Yeah, the guy who passed HS already posted the stroke would be a problem.

I'm the builder. When you hit 936rwhp and 1900ftlb on normal pump with a late GM V8 chime right in.

I don't care how many teeth each GM engine version has. 25 is close. Want to play LB7/LLY/LBZ/LMM/LML tooth counting games? Go at it. I can spot the right wheel from across the garage. And I can program/swap/fool them.

5.9 is a Dodge. Fk Dodge.

I can get laid "all day long" by your wife until you come home.

Either learn to type, learn to think, or learn to read.

The 4.25 is too big. Are the heads a 205 runner? You might just want to stick with a stock crank because those heads are not going to support a lot of cubes well. What are the rest of the cam specs?

lil john is trying to give you good advice. That crank would be a bad idea in a stock block. When done properly, sleeving the block will make it stronger and increase the length of the sleeve in order to support the longer stroke. Darton is a supplier of these sleeves and they have a 5.9 length.

lil john

Well i will dumb it down 4 U.
I HAVE A LQ9 STROKER TFS LS3 HEADS SOLID ROLLER ETC .... 4 LESS THAN
6500.oo try 2 beat that.
By the way if you have the 5.9 Dodge engine it is a shitty set-up they don't have good heads Im willing 2 bet you don't have any NASCAR HEADS LAYING AROUND. My wife told me 2 tell you that she can text you the address...so you can hook up with Miss HK 417.(she does travel alot.)
ALSO I DESIGN ENGINES I PAY 2 PUT THEM 2GETHER..347FORD/408FORD /532FORD/383SBC/283SBC/LOW DECK DODGE.......AND ENGINES ON FILE INCULDE 5.6 NISSAN 5.7 TOYOTA........BOTH STROKED & SLeeved homeboy get your $$$ right
HELL PUT THAT CRANK IN IT AND I WILL PAY MY FRIEND IN YOUR PARTS 2 WHOOP YOU

lil john

Here is a better 1 have Tony@AFR/Richard@WCCH/Steve@RED, build it 4 you the¡r ALL in the CALIFORNICATION AREA...

McRat

Here. I'll adapt to it 2014, where communication skills are necessary:

I'm playing XBox.
The deck height on the LS3 won't support 4.25" stroker cranks.
The reluctor wheels are different.
Stick with a maximum of a 4.100" stroke for that block.
If somebody tries to stuff a 4.25" into a stock block, they are an idiot.
--------- This one I'm having trouble with -------------
Use a tall deck block?
Lost me at sleeving a highly stressed aluminum block.
I buy Eagle parts for $750.


Your advice is sounds like you're very knowledgeable on the subject. Your typing skills make Kenny from South Park sound like a Harvard English Professor.

But you KNOW what they did to Kenny, right?

I'm not making fun of your advice. I just struggle with your typing skills. I'm certainly not the grammar police, but DANG, that dawg don't hunt.

PS - The Dodge 5.9 holds the diesel truck engine record at 6.25@233mph? It's a vicious engine when set up right, I just wear a Bowtie every day.

He was talking about a 5.9" long sleeve, not a Dodge engine.

McRat

Correct. I did not think you could put I6 mechanical diesel parts into an injected V8 gas engine.

For being such a badass engine builder and knowing everything already why do you even bother posting here asking advice from us mere common folk? If you were as badass and knowledgeable as you claim you would know that the idea of putting a 4.250" crank in a stock sleeve engine is borderline laughable. A piston for that application would look ridiculous. Lil John is a knowledgeable guy and was trying to tell you this nicely. There was no need to personally insult him.

lil john

Thanks brother,but people will say some of the craziest things behind a computer... Thats why I told him I love him....cause face 2 face this would not be close. Wonder if he knows some Zetas in those parts & I'm black and they call me PACO ...let sleeping dogs stay sleep.. i use 2 get mad.....joke is look at what he got and hell i got a 418 lq9 with TFS LS 3 HEADS in the closet that i have not paid to put together by LME......Since i didn't have it put 2gether I bought a lsx tall deck block...a few months ago....hell i was going 2 sell the bottom end he needs for 500 crank 500 rods...
You can only try 2 help people

McRat

Meh.

I was teasing about his unreadable post.

If you don't think he deserved that, I cry for our kids.

Here. Set your browser to Russian translation and read the board.

So I don't buy the cheap crank. BFD. Untwist your panties.

McRat

Actually, I'm not much of a keyboard racer/mechanic:

towing 50,000lb, pump fuel. 8000lb with driver.

HRP Nationals 6420lb dressed.

Blew da F up. Clocked average flying mile speed of 193 with the chute out, engine off, and on brakes. How fast did it go? No idea. Target was 215mph. 7100lb without driver.

This is a street truck. GMC of course. 25 mpg highway. 936rwhp in Bonneville trim. 800 in sled trim, 750 in drag trim.

I've raced bikes, cars, and trucks for close to 40 years now. Desert, Strip, Sled, AutoX, RR, and perhaps some I forget right now.

Building engines is something you must do so you can go race.

Yeah his post was hard to read but you obviously understood it. That doesnt give you grounds for a personal attack. Constructive debate is good, lashing out is counterproductive. Displaying your character in such a manner is a terrible way to get help. But please keep believing that sleeved blocks from erl and darton are junk and build that stock sleeve 4.25" crank engine. You are the expert after all. Just please make sure to check back in with how that works out for you.
