now those are really hard to come by. I can get wrecked vehicles but it is very rare that one of those hits the line. Thanks for the idea though.

i am only planning on spending about 2g's on the original purchase of engine, tranny, and electronics. unless an LS 6 will bolt up to my current 4L60E (93 model). i wouldnt mind having an Ls6. they are pretty nice.

do all 6.0's have 4L80E's strapped to the back of them? or do some have 4L60E's.

what is the difference in 4L60 and an M30? or is there a difference?

Thanks "Smokin rice N taken their Women"

 

Agreed!

The limit on the stock internal 5.3L IMO is somewhere around 450-500rwhp. You're compression is what's gonna keep you from running more than about 12psi on a properly sized FI unit. At least for long. I dropped compression and that has allowed me to run 12-13psi for a decent amoutn of time but after the water damage then subsequentially turning up the boost at the track to almost 15psi I have hurt something but wont know what till I tear things down. So for longevity stick to around 8-10psi on a turbo motor or 12psi on a centrifugal and you may be ok as long as your tune is good and you don't have any weak parts.

 

I have always loved the old saying,"There's no replacement for displacement." Go with the 6 liter.

 

what is the hp rating for stock internals on a 6.0 out of a truck? how common are 2wd 6.0's?

thanks

Is it possible to take a 6.0 4wd and put a 2wd tranny on it without changeing the wiring harness? how similar are 5.3 wiring harnesses to 6.0 wiring harnesses.


tell me who you think will win!

Stang thinks he can beet me, but he wont show up to race. he wants to run about a 1/4 mile on the street. ive never run a 1/4, just street racing from stoplight to stoplight. I can cruise at 100 @ 2000 rpms in fourth my tranny shifts at 4800.

use the 5.3, put 6.0 heads on it...drops the compression to 8.5. i dont see why the motor would only be good for 500 rwhp...the 6.0 is good for 600+. its the same crank and rods, only the pistons are smaller, which would probably make it more durable. put some good bolts in it, and it should be pretty bulletproof.

and you can port the hotdie of a turbo to make it spool a little faster, and flow a little more, but the wastegate only controls how much boost the turbo makes, not how much it flows. look for a pair of stock syclone turbos, or 6.5 diesel turbos if you want to be cheap....if not, t3/t4s are pretty dang cheap these days.

 

As you can see severed ties, all the LSx truck or car motors are externally identical as far as mounts, head design, layout, etc.
There is definitely more potential in the 6.0L motor if future HIPO mods are in your plans. If this is a daily driver, for sure the 5.3L will serve you quite well. Also if you plan to mod later the stock 60E tranny will probably not survive the extra HP. Look at one of the newer 65E or 80E trannies.
Also, your 4L60E should be a match to the LSx GenIII motors. Only difference is that there is one less bellhousing bolt on the GenIII motors ( top around 1 o'clock area ). This would just go unused on the swap with no worries about reliability. Not sure on the harness for 2 vs 4wd but check the LS1/LS6 engine section as I'm sure someone has done this.
I think you are in need of some oil pan mods and possible cross member mods if you intend to use the LSx A/C compressor. There are quite a few shops making conversion kits for older Camaros and Firebirds, I'll look up some names and post for ya.
Good luck, keep us up on the swap!

 

thanks man. i appreciate the info on the swap. it will be a daily driver. by the way the 4.3 mentioned earlier is the engine being replaced. it runs ok but laks the real horses i am looking for. sounds like a very large pissed off bumble bee with somthing stuck in its throught. hehe. very unique sound.

Thanks

 

I say about 500rwhp is near the limit (for daily driving) due to the higher compresison of the 5.3L. You cannot run as much boost safely on pump gas. True you can add methanol as a suppliment but you are still asking for trouble IMO as a daily driver.

Keep in mind that not many people on this board have run 600rwhp on pump gas on a completely stock 6.0L. Only one I know of that was even close is Parish and his setup was on race gas and we don't know for how long he would have been able to run on the street with that tune because of the nitrous problem.

I'm not saying 600+rwhp is not possible on a stock 5.3L (stock compression). I'm just saying that I wouldn't call it a safe daily driver unless you only boost it once in a blue moon.

 

see that's why I would do a dual boost controller so I can dick around with 5 psi and have the meth. injection kick on when I go above 7 psi when the controller is moved. that's the best idea I have come up with.
