The fact that DC did copy a lot of the LS1 design can't be disputed though.
Welpers, first...

You can have your 15lb-ft (if that's accurate), I'll take the 55hp and the aluminum block, thanks.

like what, because that's a more fare comparison than between engines of the same size and output? we'll see how favorably the LS2 compares to the 6.1L H when that comes out, mmmkay?

LS1 is an old engine (1997) LS6 came out around the same time as the hemi and both are 5.7L

LS2 vs. 6.1L Super Hemi should be a fair and even mathc up.

Keep in mind that the LS1 was very under-rated from the factory (esp in F-body trim). Mine put down 339TQ to the wheels when bone stock. That equates to around 390TQ...

Here's a good one.

http://home.att.net/~marksmoore/Weights.htm

Edit: Why is the L98 so damn heavy? As heavy as the LT5. It's listed as 600lbs. Even if all iron, it shouldn't be that heavy.

L98's were all iron, at least up to a point.

But hell, GM hit on a badass runner design, and Im all for Chrysler using it as a base to make more power in their own cars. Thats what LS7 is for.

Maybe Ford could even use it in "Hurricane," instead of that horrible thing they call an intake runner in the 4.6s...
Lets see Ford has had that set up as early as 1994.

Canted valve is nothing new, BOSS 351/302/429 Mustangs used them ALONG time ago. Just like a BBC.
There are alot of Ford idea's in a LS series engine. Just look at the intake valve and exhaust valve order, And compare to a SBF. It is'nt following the OLD 350 intake/exhaust order is it?

That was one thing I missed, thanks for pointing it out. GM copied lots of things from small block Fords. Canted valves have indeed been used on lots of motors, most notably the Big block Chevys. (The Fords, while badass, were mainly hi-po limited production motors, excepting the 351C, which still didnt get produced for very long.) The Boss9 motors were very near to the ideas from a 426 Hemi grafted onto a Ford big block.

That kind of thing works great. GM used the Ford firing order and other details, along with revolutionary heads, and a very stout shortblock, and created a motor that outperforms almost anything else GM has ever offered. Chrysler has recently attempted to do the same. Only time will tell how effective it's been. With any luck for you Ford guys, "Hurricane" will make ditching the Mod motors a reality, and then maybe GM can steal some more ideas from you.

Re: Interesting LSx factoid...

What sucks the most about the mod motors is one thing. They were designed to fit into the Lincoln Continental, You know that front wheel drive thing they DON'T build anymore? Is'nt it a _______ when some dumb ________ design engineer can screw such a good thing.?
The guys designing the mod motors were highly pissed about the changes they had to make for the Lincoln. They "took" away alot of the good from it. But I will not say it is a bad engine.

Thats the root of the mod motor's problem. They sacrificed in a BIG BIG BIG way to make that thing fit in a FWD application. Did they ever even use it as such? I dont even know.
