This thread needs more Gen 3 hemi's.
This:
with one of these shiny things...
Should make a 3400 lb car with a 4 speed and a Dana go into orbit...and then I can turn up the boost.
9lbs on a similar build to mine took a 4300 lb wagon to 1.53 60 foot and 11.0 @ 124...
And I really won't have much at all into it. There are a ton of guys switching up parts over on LXForums for cheap and the fact that there are millions of cars in junk yards makes piecing this stuff together easy.
LsWHAT?
More Hemi..OK!! The LS guys are using stock short blocks. This is what you get using stock crank and block from the hemi. I am thinking the GM guys have a better starting point. 
Yep, that's the Achillies heel of the HEMI, they are very sensitive to boost and can't take what a stock LS can. Throw in a proper set of rods and pistons and its a different story

NO boost,,,and a proper set of rods and pistons were used. All indications point to a poor oiling crankshaft. Before anybody says..."you have to use the 6.1 oil pump"..this engine had a Barnes oil system. I am a Mopar lover/racer, but, the GM people seem to have an advantage in what is available to work with from the factory and their factory seems to work with them.
If you like drag racing, support your local track.

Ah that's the dirt track engine you built, if I remember correctly it suffered from the same problem that the Drag Pac cars have, high rpm oiling problem (7500+) and takes out the 3&4 rod right? Only a couple of guys (Barton for one) have figured the "secret" it seems, something about oil leaving the crank oil passages at high rpm. Supposedly you can redrill the passages or an aftermarket crank fixes the problem.
Have you figured out what the problem was/is?

If you do spray a stock LS engine, at least pull the pistons out and open up the ring gap. Any stock engine for that matter.
Not saying that's not a good idea (b/c it is), but there are a ton of fast GM LS motors being sprayed a lot that have never had the pistons out the block and last a long time.
Here's a simple combo that works...good friend of mine has a '98 Firebird. Stock LS1 shortblock except for ARP rod bolts. Ported factory GM 5.3 truck heads, 240 at .050" cam (hydraulic roller) w/ around .600" lift, FAST intake, headers, 4000 stall, 4L80E OD truck trans, 4.10 geared 12 bolt...3800 or so lbs (nothing taken out of it), still has A/C, cruise, and all factory stuff.
It's been 10.90s on motor and pump gas. On a mild 125 hp shot he's been some tire spinning low 10s at around 134-135 mph. It'll go 9s w/ traction. His wife picks their kids up from school in it, lol.

Well said! For me Fiat has to release the encryption software. Once this is done sky the limit.

2010 down aren't encrypted and you can tune to your heart's content....
gen3 hemi's have some inherent advantages over an LS (their more accurately described as polyspheric) head geometry is such the the valve opens away from the cyl wall, reducing valve shrouding for one...
don't see the point in an LS swap....around here, LS motors are just as expensive as gen3 hemi's...used 6L's are going for $2500+, 6.2L's in the $5k range...

Now back on track show me some 100% stock block and heads LS without the Boost and Giggle juice.
Throwing boost on anything kind of negates the $$$$ factor. That crap is expensive on a cheap day for decent parts. (NOT E-Bay China crap either).
Stock Lq4 6.0- $875 to my door
L-92 heads- $890
GMPP hot cam kit- $364 my cost
carbed intake used off ebag- $200
gaskets, oil pumnp, and misc.- $300
Headers off ebag- $200 i think
Grand total of $2829 on hard parts. This is what a friend of mine put together for a customer. With a TH350 trans and big converter it made just a shade over 500whp in a 70 nova. I thinks thats pretty darn good for a N/A pumpgas roller cammed smallblock.
Boost doesn't have to be expensive. ALL my turbo parts are from ebag and china, all were cheap and none have given me a minutes problem. The car is driven/abused atleast 3-4 times a week

Of all the dumb things people do to their Mopars, this is the absolute WORSE thing I can think of. It`s totally disrespectfull and embarrasing...................  
Seems funny to me, that in the past 50 or so years, it has been perfectly fine to put a chrysler hemi in just about every car ever made, including fords and chevys. Conversely, it is blasphemy to install a new LS engine in a old mopar. The reason people put a hemi in their cars back in the 50s and 60s, is because the hemi was a better engine for making power, and the after market was supporting it with cool parts like superchargers, pistons, cams, ect. Seems to me, in todays world, the GM LS engine is the better engine for making power. The LS conversion trend in all makes of cars will not stop, because they are well built, well engineered, smaller, lighter, cheaper, extremely well supported by the aftermarket, and make more power per dollar than anything else. I am a mopar guy to, but holding on so strictly to brand loyalty is silliness. How is this disrespectful and embarasing? What about upgrading to cal tracs, GM powerglide trans, Ford 9" rear end, MSD ignition, etc, etc. Why is this considered acceptable with everyone including the new superstock Dodge Challengers? Is this only because you can hide a transmission or rear axle under your car, but an engine is easy to see? Is this a religion or a hobby? I have never seen the book of rules of what you can and can't do with your car. Do what you want and enjoy your car while you can.

That`s what forums are for.........different strokes,different ideas and opinions. I could care less if an ls-1 was free and made 800hp on pump gas, there`s no way I`d sell out my dart to that crap.........ever. SILLINESS is your reasoning for why it`s NORMAL and HOT RODDING as you call it..............

No LS1s in a Mopar around here. I caught so much crap in my life that a SBC will make my Dodges run better, only to prove them wrong week in and week out. I won't be putting Chevy power in anything thats not Chevy........... However, my Ford friend and I have always wanted to take a 57 Chevy and put a 440 in it, so it runs properly, and show it often. That should make up for all the "hot rods" running around with a "tree-fity" in them.  Michael
