LS Square Bodies?

[Joshua8336]

anyone on here got any ls based engines in their square bodies? if so, POST PICS!!!!!! I'll start.

I've just kicked my conversion off, so it's still in progress. Plans are to get this puny 4.8 liter going while i get a 6.0 built.

I know of several in progress, but none that are running as of yet. A couple of them are on this site.

i am getting ready to do a 6.0 . but would love to see how yours goes .

thanks! i myself am stoked about it. it's been in my family for a long time. i will be keeping the fuel injection for better gas mileage. set on the iron 406 stroker. will probably be putting a fast 102, 317 heads, 238/240 cam, and a 4,500 stall all through a built stage 3 rossler 4L60E. Wiring thses things isn't hard at all. A build thread will be in the works soon.

Yep, flaming6.0 (I think that's his screen name ) is in the middle of his build right now with a 6.0 in his square. That'll be a wicked setup! I hope to do an LS swap in the future on mine. I'm thinking 6.2 out of an Escalade

To be honest, on a build like that, why do you care about mileage? I sure wouldn't want to be driving that on the street anyway. I hope you are planning on porting the 317 heads, because with a 238/240 cam, you are going to be running out of breathing room with those heads, especially on a 406. The last thing you want to do is have such a huge cam that you have no bottom-end, and then have no top-end flow because of your heads. That leaves you with a very narrow mid-range pull, and, to be honest, a dog of an engine compared to what it could be. AI does some really nice CNC porting on the 317s/243s that would be more appropriate for that cam.


I'm planning on an LQ4 with CNC'd 243 heads from AI (243's with a 64cc chamber will get me around 10:1 compression) with a nice mild bump stick. The AI 243s will gain probably about 20-30whp over stock 317s themselves, plus the bumpstick should add around another 30-40whp when combined with the heads. The nice thing about AIs program is that they focus more on port speed than flow, so this thing will still give you a kick in the pants down low, and pull hard up top with the additional airflow they provide. 400+whp and a killer bottom end? I say, why spin it to the moon if you don't have to?

317's will be sent to TEA for porting.

317's will be sent to TEA for porting.

Eeeexcellent. Can't go wrong with either TEA or AI.

 

[Joshua8336]

any it will be daily driven

 

[johnmc]

is there anyone on here that can reprogram the icm to except a larger cam?

 

[Joshua8336]

you must have some kind of tuning software. ex hp tuners etc. i would just have VATS tuned out of the PCM and then when your done take it to a tuner in ur local area.

 

[Old77]

Black Bear Performance might be able to help ya

 

[Bagged Dually]

Did I read that right?? A 4,500 stall for a daily driver??

 

[Joshua8336]

yea, plans have changed. 3600 stall through a 5.3 with a 224.228 cam with ls6 heads and valves and a fast 92/92 combo

 

[Manbearpig]

4000+ stalls are very daily driveable on 60e and 80e trucks
