nice addition to the site. super chevy for sept. has an article in it about ls engines. 400cid, twin 88 turbos and 2,050 hp at 7,140rpm and 25lbs of boost. GMPP put it in a full frame 96 impala ss built just for this engine. from the front vue of the car, looks pretty wicked with skinnys up front and what looks like fairly wide tires out back.

With all the xtra traction the dual rear wheels would offer with 4 cheater slicks back there, I'm afraid it might flip over backwards from all that horsepower.

How to build a 550 horse motor


350 MUST BE A 4 BOLT MAIN out of a corvette... bored .060 over ( doesn't have to actually be bored just say it has been...and always .060 never .030)
Aluminum "High Rise" Intake
750 "DUAL LINE" HOLLEY (this can be ANY carb that says Holley on it)
2.02 Double Hump heads( do not need 2.02 valves even 1.94 DH heads automatically have 2.02 valves )
3/4 cam or Crane fireball 2 cam
chrome valve covers

Turn the idle speed screw down so the engine idles at 175 rpm

We are getting old, the LS is the new GM small block. How many old GM 350 blocks are left? The GM 454 blocks are gold around here. The cost of aftermarket blocks will make the LS more popular before it is over we will all probably run a LS motor at some point. Think in the 70's electronic ignition and disc brakes, 80's fuel injection that would never last. Change scares people, but is sometimes for the best. Just my 2 cents!

I HAVE A 2003 LS1 IN MY 57 CHEVY AND LOVE IT... THESE LS ENGINES ARE BULLET PROOF COMPARED TO THE OLD SCHOOL STUFF... A GUY IN TOWN HAS ONE IN A S10 WITH A BIGGER CAM AND SPRINGS,, RUNS 10.80 AND DRIVES IT 120 MILES ONE WAY TO THE TRACK AND GETS 20 MILES TO THE GALLON... THIS IS WITH A 900.00 JUNKYARD MOTOR
A STOCK STYLE NODULAR LS CRANK WILL HANDLE 600 HP
STOCK RODS WILL HANDLE 550 HP
THE BLOCKS ARE 6 BOLT MAINS AND WILL HANDLE 700+ HP
THE HEADS STOCK HAVE HUGE INTAKE PORTS AND BREATH WELL..
RIGHT NOW YOU CAN BUY THEM IN ANY JUNKYARD FROM ROLLOVERS FROM 300.00 TO 1200.00 DEPENDING ON MILEAGE... I HAVE BEEN RUNNING OLD SCHOOL MOTORS SINCE 1990 AND THESE LS ENGINES PRODUCE WAY MORE HORSEPOWER....OPINION

I really like my ls motors. I've got a little new and a little old in my 2000 Trans am. Ls1 motor and a trans braked turbo 400/12bolt driveline. I'm kinda kicking myself I didn't step up the the 4l80e trans but the th400 is just so much more cost effective.

Whelp, I certainly don't want to be the bearer of bad news, but my boy has an LS1 in his C-5 Vette. It's beefed up and has a 500 shot multistage nitrous set up on it. He is not too hot out of the hole with the stock vette suspension, but is is still purty darn quick. I hate to say it, but he has run the snot out ouf that motor.

I actually look for this thread to become quite popular once the word gets out. We just need to find a few LS guru's to help it out.

I have seen the LS motors handle a lot of power ie. nitrous, turbos and prochargers making well over 1000 hp. Not to bad for a small block.

As far as working on them, its not too bad once you have been through one of them once or twice. The 6 bolt main caps on the ls motors are a tad bit stronger than conventional 4 bolt main SBC's.

Can't punch these blocks out .060 over. These bolcks are not designed to be bored out at all.

We disassembled the top end of my boys Ls 1 put on a new oil pump, timing chain and gears, LS6 heads, new cam etc. Took about 12 hours from start to finish. but aftermarket parts like the oil pump do not bolt right on. It takes a little milling on the pump and timing cover to make everything fit on some applications.

The head design isn't to bad either. We did quite a bit of test porting and flow checking. Word to the wise, DO NOT REMOVE ANY MATERIAL FROM THE BOTTOM OF THE RUNNER, """YOU WILL LOSE FLOW"""

Removing material and polishing in the upper portion of the runner and down the sides mid way increase your flow considerably.

I am with you on this one tod74.........

I myself must admit, I have had my share of 500+ and 600+ cubic inch motors and I have came to the conclusion that if the motor is not over 500 CID it is not going in my car....................

Small Block Guys are always bragging about how they spin their small blocks to 8 grand, Well I spin my BBC to 8 grand, You don't see me braggin, Well. maybe a little.

All this talk about BBC vs. SBC vs. LS MOTORS, HP capability and engine reving is starting to boil the blood. Its' time to have another fun day tinkering around.

I think you cannot deny the cylinder head capability. In the GM catalog they have a new head coming out called the LSX-DR for drag race. It has a 2.25 intake valve and says the head is capable of 430 cfm. There is where the difference is going to be. That will be a fast cylinder filling port. I am ALL IN with the LSX block and that head with 454 inches. That LSX block can be bored to 4.250. I want to go 4.185 and 4.125 stroke for a 454 on pump gas. It will be a torque monster Im sure. BUT I still have a 406 and a 565 old school. They will continue to stay home with me.

In fact the unported L-92 cyl head flows in the 316s at 600 lift with a 4 inch bore. GMPP catalog is only 5 dollars, go get one this engine platform is awesome!

I have been working on these motors for 4 years now. I'm amazed at the technology that can deliver 23-28MPG with 400-600HP, and 9-11 second track times in 3300-3600LB cars. Most investments are $4000-8000.00, as the heads, intakes, and related accessories are still up there in price. The Auto OD/6SPD trannies are pricey also. The diffs are comparable to the old school stuff, unless going to a sheetmetal 9". GM High Tech is the Bible of choice for good info.

The DR-LSX heads are stricly race and big cube at the flow numbers advertised-422-430CFM. We are hoping that Chevy comes out with a DR-LSX 330-380CFM head for the street guys. Most of todays heads are CNC'd for 330-360CFM-I, 240-260CFM-E, whether stock style or aftermarket.

The tuning is the issue today. There is a killing to be made if you can tune an EFI vehicle. I am being educated as I write.

The event of the year is the LSX Shootout-Oct, 15-18, in Memphis, Tn.
If you want to see Big Block killers in street form, this is the place. I still have a 540, but the LS motor has similar power and much better mileage, Damn-I never thought I'd say that in public!!

Good Luck, People!

Well, I recently started racing again and I have a 97 Camaro with a ls1 swap. The motor is all stock except for a intake and throttle body and headers and its running 7.35 in the 1/8 all day long consistently, very consistently depending on the track. I drive it on the street also.

GM really has done their homework with these motors. Im building a 440 cid LSX block based version. I have the short deck LSX block, but you could still max this thing out at about 480 cid. But my goal it too build 1200hp streetable, and thats not hard with a turbo or supercharger! Plus id like too leave room for rebuilding if i have too. I would go with more cubes but normally anything over 4 inches of stroke isnt good for the street.

The LSX block can handle up to 2500hp, and thats some serious power for a small block. Not to mention the heads alone are six bolts per cylinder, and push 370cfm on the intake out of the box. The skies the limit with this block!

Also, the aluminum production block isnt a bad choice either, the weight savings alone makes this thing a great selection for racing if its setup right.http://lh3.ggpht.com/_ASmrlNtnesc/SOvnMNN3bmI/AAAAAAAAAR8/shd02tGMruA/s640/DSCF0791.JPG

So far all I have is the block, rods and supercharger. Rods are callies compstar 6.125 inch, and the supercharger is vortech s-trim. This supercharger is only good for 700hp so once i get the motor running good with it im gonna have to upgrade to achieve my 1200hp goal :D

I have the LS1 - basically stock in my 99 coupe - 6 sp, 3.73 rear, better intake, exhaust and brakes. I think the L! series are the best SBC ever built - can drive at 650 rpm in 6th gear, never lugs - thus really fantastic mileage. Must be mostly due to SFI. Many major changes from past 350 SBC, even different firing order.

My two sons run LS1's in there 2001 trans am and 1999 camaro SS. Tim's Orange 99 Camaro was the one that you saw on PINKS. I didn't know much about LS1's a few years back but now they are pretty cool motors and make tons of power. Tim runs NHRA C/Stock now in his Camaro. We built the motor and it has ran 10.70's with a lot more potential. Todd's Trans AM with cam and gears ran 11.50's with a stock rear end.
There is a web site www.ls1tech.com and check out the forum. These guys know everything about LS and LSX. Pretty cool stuff and I'm an old school guy that still runs a carb and always will :lol:
