For the LS engine lovers
 

Thought maybe you LS guys would like this build. This one here in the article is a great piece, but they've took it even further now. New setup is the 4.5L whipple. On race fuel 1450hp. They also have a pump gas setup, and pump gas with water/meth setup they are playing with. Granted, not a "marine build", but, either way, cool build.

Looks like a nice package.

It needs a few more pulleys.

Don't worry, I'll put the brass freeze plugs in...

"engine is about 10.25:1. We overbuilt the engine – it’s capable of handling up to 30 pounds of boost" :eek:

That's the only difference right??? lol

I was involved with a local drag race shop building a 427 LS about a year ago. I sold them the 4L Whipple and helped get it built and tuned. It made just over 1000 hp on 93 octane. Never did a race gas tune. I wish we would have as I would have loved to see what it could do on some good gas. All in all, it was a cool piece that made great power.

Also, a little bit of chrome would have dressed it up a bit....talk about plain jane....haha

I wish someone would talk gates into ditching that green color on their heavy duty belts.

One of my girlfriends is in sales at Gates. I'll have her put that in the suggestion box.

I read it on the internet so it has to be true. lol

to put things in perspective,this engine was built for a customer at a cost of 42,000.00.

What would it cost to have a big block built in that same power range? I seriously have no idea as its all out of my price range, but I would think it would be about the same right?

pretty cool..and $$$$ here's a pic of my 1200hp street LS, 370ci using stock intake and exhaust manifolds, 25psi on E85...not pretty like this one...but with hood on....

i would think a big block build of that caliber would cost pretty close to that price.high end parts are not cheep.i spent some crazy money when i built my 588s.

that is 3.24 hp per cubic inch,very impressive.

It is about the same amount whether you build a BBC or an LS of the same power level.

What would be the pros/cons of each motor?

Efficiency, better valve train geometry? Etc.

The LS is smaller and more compact. It also weighs less. However, it doesn't make the torque that a BBC does. It's not that much less, but less none the less. It's different., I guess, is the big draw. At least for the marine side. The automotive guys have embraced it like nothing else in history. The LS's are a great choice for a smaller single engine boat, or maybe a 28-30 twin that would normally have small blocks. It can take the place of a BBC, but it would have to be built pretty tough. The availability of parts isn't what it is for a BB. That's why the cost is roughly the same. As more manufactures come out with new parts for the marine side, the pricing will come down. It's still a viable option for just about anything other than a HUGE boat that wants/needs a ton of power.

Looks like an aluminum block also, that thing must be plenty light compared to a BBC. I am curious how well the aluminum block does with deflection at that power level compared to an iron block.

I didn't read the article so maybe this was stated in it, but is that front accessory drive from Wegner? That's what we used. Looks the same. They have got it all figured out to work with a Whipple.

using high boost, 20psi and over not sure about the aluminum, recommend the iron block, and we run those 1/2 filled to keep the cylinder walls from loosing roundness under boost. I never realized this until taking at length to weisco, they said done lots of test and showed cyl walls not staying round, even with the iron blocks, so we do this to keep ring seal...did not effect running temps or iol temps with the E85

whats that drive setup cost?

A little over 3K with everything. It's all really good parts like a Powermaster alternator, OE p/s pump and water pump, Sanden A/C compressor, all the billet brackets and pulleys, hardware, Gates belt, etc. It is well worth the money. It is designed to work with the Whipple and uses a common belt to drive the blower.
