Generation IV Internal Engine - Our LSX is done

Well we have had a lot of issues and setbacks but our LSX is done and should be running on the dyno shortly.

Doesn't look like many LS engines.

Here is a picture. The guy in the GMPP garb is the engine builder Jeff Stealy. Jeff has worked his butt of on our Nitrous 454 LSX engine. If it bolted to the engine it had to be modified in some way. Jeff has the ability to get things done.

If you guys want to purchase an LSX hat and/or GM Performance Parts T SHirts they are selling online over at gmperformanceparts.com.

Thanks

Robin

HOLY.... that is amazing, and i want one.. great job guys
how much power you think ur guna make?

motor is beautiful.

his face says:"it sure is pretty, but god damnit...never again."...lol.

Nice work Robin. :thumb:
It's nice to see a few large displacement builds up and running. They're sure not an easy bolt together. :eek2: Lots of detail and fitting to do.

Congrats on finishing this project. :cheers:

Richard :)

That looks nothing like an LS motor, lol.

I know, I was thinking the same thing.

Super nice. Any word on the power output?

D.J.

that's really nice

That should put out a nice solid 300 HP...350 tops :jest:

Very nice. x3 on power out put.

I am assuming thats a magneato setup that your running.

No, that is a MSD Universal Belt Drive Distributor. It has a 1/4" belt that is driven off the front of the Jesel Belt Drive. The MSD Digital Programable is triggered by the Crank Trigger.

Looking for power on Motor in the 950+ range. Will spray an additional 4 to 5 on a NOS Pro Fogger single stage.

Richard, thanks, you understand how much it takes to get something like this done LOL.

Robin, what heads and bottom end components are in the motor? Compression ratio?

The motor looks very good! :)

Jason

So that must be a Pro-jection throttle body then. Funny, I can't see the fuel injectors. Must be a new proto-type from Holley!!!! LOL
Robin, why is the first GMPP's 454 not fuel injected? Seems to me this is a step in the wrong direction. I realize that sanctioning bodies mandate carbs and all, but you guys have pull there at the General and it is time to get EFI regulated in all racing classes. If you guys can't get the rules to change, none of us will be able to. Just a thought. Nice work though, that thing should put the old SBC's in the garbage.

Awesome build up, me and my dad have talked about doing the same type of build up for our Top Sportsman truck. It will be interesting to see how its going to run.

Lunati Crankshaft

Compression ratio is 14.5 to 1

It took a ton of work by Jeff at Stealy to make this deal work.

i think i need a new pair of shorts. that's gorgeous - i might buy a ring for it and propose...

i have the same pistions and rods, so i should be about 900 hp. lol jk.
looks great, man i was hoping you used a stock style oil pan. im tweeking over the grp rods hitting the oil pan, and i still dont have my parts back to test fit everything. doh.
when will it be in the car?
good luck for sure!!


off topic, tex, great looking set up :chug:

Nice Robin...almost thought that was Moran when I opened the photo :)

Thanks Noyzee. I cant wait to build the LSX block next. I have one sitting here at work. I am just waiting on the heads to get started.

I gotta know, where did you get those valve covers!?

They are GMPP valve covers. They are a little over $100 apiece. He had them powdercoated/painted. I really like how he recut the grooves, looks really, really good!!

where did you get the wire holders though???

Super nice Robin! Can not wait to see this motor and car go down the track!

looks like a bigger version of my engine. I like it though. What kind of vehicle is it going in. Sorry I am not as familar with your setup as some of the other guys on here. Here is a pic of the engine I am working on currently.

Wow. I like what you did with the spark plug wires.

Well my machinest Bryan made them for us. You cant see it in the pictures but there are looms under the manifold made out of billet that hold the wires in place. Every custom part you see on that engine(and even some that you dont) Bryan made. If you like those you sould see his billet aluminum engine mounts. Oh and after we powder coated the valve covers he went back over and ball milled them along with the valley cover.

I noticed that. I was thinking about having mine done.

I can't tell you how good that looks!!!! :drive:

Yeah those are some of the nice finishing touches that Bryan does for us when he does an engine for us. Everytime is different though. depend on what mood he is in i guess.

Will the routing of the wires work like that once the headers are on. Looks like some are going right over the exhaust ports. Could be the angle of the picture though. F'ing beautifull, regardles !!

That looks nothing like an LS motor, lol.

Looks like a miniature Pro Stock motor.

Does that intake have the tube that runs inside (down the length) with the nozzles that spray right into the runners? I cant remember the name of the system now.

Cigaro?

That is an awesome looking setup. Not to keen on the distributor, but it looks awesome. On a side note, be carefull with the timing pointer on the balancer like that. Those balancers have a tendancy to slip, which would reak havok on your timing. Good job though.

man that looks killer!! :headbang:

It's on the dyno and we fired it up.

More later

The wires clear the headers no problem. They come down in the same locationa as stock.

Not if your running a Crank key.

Cant wait to see wht kind of numbers that engine puts down Robin L

So that must be a Pro-jection throttle body then. Funny, I can't see the fuel injectors. Must be a new proto-type from Holley!!!! LOL

In the NMCA NPS class EFI is allowed! :judge: Schroeder's NPS 02 Camaro 632ci has EFI! :devil:

Hahaha. yeah I am a lot more comfortable with Fuel Injection than the carbs. As stated above EFI is allowed in NPS with a weight penalty.
With the new car and engine program I felt it would minimize the complications by going with carbs.
I still have to sort out the Nitrous and the clutch.

I may look at EFI once we get this thing sorted out. With the carbs we are using working so well I may just stick to them.

Not to mention you can make more power with carbs.

Cigaro?

Yeah, that's the system that I was trying to put my finger on. OTZAL is what they call the spray bar that goes inside the intake, I think.

It's on the dyno and we fired it up.

So what did it make?

Well, while not the 950 that I wanted am pleased. It made 930 at 8400 RPM. It made 666 Torque at 6600 RPM.

Watch for yourself.

Are you running GMPP LS-7 heads on it or aftermarket? Has a nice crisp sound to it. Just saw where you posted about the heads being C5R's.

D.J.

What size cam are you using? I imagine you may not want to share that information, but that would be helpful. I am trying to decide on a cam for my 454 LSX which is waiting for a cam at the moment?

made 666 Torque at 6600 RPM.

Robin


It truly is a beast....
