LT1 hate or just stupidity?
Everyone that ive ever raced. With my car going from stock to bolt ons to cammed. everyone that ive ever raced or have given a ride to is impressed with the power it puts out for the money ive spent on it. Over all for a very strong easy to work on engine. its hard to beat
Better heads, better intake, better cooling system design, better priority oiling, better block (6 bolt mains), stronger stock pistons and rods, better ignition, better "everything".
BTW These LS cars are not dynoing 400 RWHP with a "baby" cam...
It takes a very healthy cam to do that, with bone stock heads.
Get a good port job on the heads and it's easily doable with a mild cam. 450-470 is doable with a GOOD port job on the heads and healthy cam.
500 RWHP has been done on 346ci engines with top of the line parts. That usually doesnt happen with LT1's...

Verdad Gallardo Dyno numbers are subjective. In my experience it takes a healthy cam to put 400 at the tires with an LS. Not a slam on them, just my observation. There are always numbers on the high and low end of the spectrum but I'm talking average.

those of you comparing aftermarket to aftermarket need to stop.
gen 1 sbcs were making 1500 hp on "stock blocks" long before the (gen 2) lt or ls even existed.
the ls1 is superior to the lt1 in every way, shape, and form. this is not news. i don't see the LT9s in the new vettes, or LT3s, or LT2s for that matter even. there was no reason to surpass the 1 as something new and better had been in production for a long time. hell, i am pretty sure the original lt1 made better power in stock trim than the *new ones did.

Sorry I gotta dissagree the main reason I went LT1 in mt 1997 K1500, is the sound and feal of the LS series just aint a true old school Chevy to my old bones they may be better? ok but I aint ready to jump yet, love my LT1 w/distributor. I test drove one of the new/old mustangs thinkin "hay old school hot rod!!!" but just couldn't get past that ford sound and feal, couldn't make myself buy it LOL
I know that this chart may not impress you big boys but here is my LT1's chart; stock motor, distributor mod, shortie headers, and stock 2 inch twin exaust with cats intact. the timing is about 10 degrees slow, and I havend worked it for more, so you know there is a lot of power still on the table that I could pull out.

I am currently making plans to put an M90 or M112 on the next "LT1 motor build" done my way "again"

You're showing your age. The LT-1 was a solid lifter 11:1 sbc 350 from back in 1970.
Last year VETTE magazine ran a stock LT-1 and LT1 on the dyno and they made within 5 hp of each other.
EDIT: From the Aug 2010 issue of VETTE magazine.
Both engines run on 1 3/4 longtubes with 1970 LT-1 additionally using a EWP
1970 LT-1 353 hp @ 5600, 392 lbft torque @ 4100
1996 LT1 351 hp @ 5700, 379 lbft torque @ 3900

regardless: 300hp - 15% drivetrain loss = 255rwhp
351hp - 15% drivetrain loss = ~298rwhp
Thats a 43rwhp difference with only longtubes in a stock lt1. Seems kinda stretched to me whether its a vette or f-body
