shotgun 04-25-2005, 04:55 PM GM already makes a ZL1 crate engine based on the original zl1 block, http://www.sdpc2000.com/catalog/120/products/153750/ZL1-454ci-510-HP-Fuel-Injected-GM-Performance-Parts-Crate-Engine.htm
I vote we use that :D
Jackal 04-25-2005, 05:18 PM use the LS7, "detune it" a bit, so old man vette doesn't get mad;)
Z28Marcus 04-25-2005, 05:33 PM use the LS7, "detune it" a bit, so old man vette doesn't get mad;)
LOL. Yes, like 4 Hp due to an easily removable air-box baffle :).

Yeah, but what I meant by detune was bullsh!t horsepower ratings, i.e, Rate it at 475, but make it clear to the enthusiasts that it's RWHP, not crank HP like it says on the sticker ;)
0toinsanein5.4sec 04-25-2005, 07:08 PM i am all about the NA LS7
Abidar 04-25-2005, 07:17 PM I'm all about a ZL1 camaro... :D
Gold_Rush 04-25-2005, 07:21 PM If they build it right, i'd welcome the supercharged ls2. And by built right, i mean forged internals and with 700+ hp just a pulley swap away. Then perhaps that'll put an end to the "well, if we put a supercharger on Lsx" argument we've been hearing ever since the Cobras went supercharger:p ;). hehe.
But the Ls7 would be my engine of choice. Just something about having 427 cubes under the hood:D. Ford basically used a detuned Ford GT motor with the more exotic stuff replaced with conventional parts and so GM should go that route to bring costs down while giving the z06's Ls7 exclusivity. ex: Replace dry-sump oiling system with conventional sump, replace titanium rods and valves with more conventional ones, etc.... Do so that price comes down significantly, but performance doesn't suffer that much. Since the z06's Ls7 is certified (accuratly) at 505hp, such ZL1 should come in at around 470hp. That should make it very competitive with the GT-500, especially if the camaro turns out to be lighter.
In reality, i'd be very happy with either and we'll be very lucky to get either one. Wishful thinking for now, but one can dream.
BLACKBIRD8200 04-25-2005, 07:30 PM IF they just put the LS7 in it the old ZL1 (2002) would have more power.
if they make a new ZL1 it has to be better then the old one and the (2002) had like 600hp and 575tq
HAZ-Matt 04-25-2005, 07:34 PM FI > NA
EDIT: For some reason my post was Fi > Na... don't know why Fi would be greater than sodium :)
jg95z28 04-25-2005, 07:48 PM use the LS7, "detune it" a bit, so old man vette doesn't get mad;)
Yeah... just like they "detuned" the COPOs and Yenkos. ;)

First of all, it was a limited production run numbered crate motor, and second while it played homage to the original ZL1 block, it was not based off of it. Besides, all those that bought the special ZL1 crate motor would march on GM if they all of a sudden ramped up production again. :think:
The LS7 crate motor is what half the price? :p
I also want to know who in their right mind voted for the supercharged LS2, and what their reasoning was? That combination should be more slated for a production SS and not an ultra exotic that would be the Z28... er I mean ZL1. ;)

I think Haz-matt voted for the S/c'd Ls2 judging by his post:D.
It's still a great engine though. Just look at Ford's blown 4.6 and 5.4's and the potential of a well-built factory boosted v8 engines.
True, the Ls7 is more exotic, but you know what that means? more expensive parts. 700hp would be a breeze (and cheap) for a blown and forged 6.0L Ls2. It wouldn't come as cheap on a modified Ls7 though.
Both are great engines. I'd rather have the Ls7 just because 500hp is more than enough for me and i'd keep it stock, but for those wanting more without breaking the bank, the S/c'd Ls2 would provide some good thrills.
number77 04-25-2005, 08:29 PM the old zl1 had more power than 505hp so the new one should. i say do the iron 572 (like Moss's aluminum 572). :shrug:
The only way i think that that would happen though would be if GM let people buy camaro and get the engine dealer installed.
i figure if you do it, go alllll the way. remember that their were 69 original zl1's. why would you want to dishonor that name with a "mere" 500 hp?
::i know i'm being unlrealistic, but i enjoy that:: :)
OutsiderIROC-Z 04-25-2005, 09:48 PM All aluminum 427.
uluz28 04-26-2005, 09:18 AM Give me the charged LS2 with forged internals to take the beating (while we're fantasizing). That'd be a recipe for a cheaply modded beast of a car...
PacerX 04-26-2005, 09:34 AM LS7.
Less weight, smaller size, less complexity, less $$$.
If I'm going to mod it, I really don't care if it's FI or not. Running nitrous without preparing a motor for it is begging for a big BOOM, even if it is an FI motor from the factory, so that means the modability of an FI motor is in my mind not advantageous enough to make me want to sacrifice the weight and complexity issues.
From what I see, an LS7 with lower compression pistons will be an amazing FI motor. So, if that's your thing, go with the LS7, swap out the pistons and bolt on a blower.

Chris 96 WS6 04-26-2005, 10:14 AM the old zl1 had more power than 505hp
Are you sure about that? You're looking at SAE Gross v. SAE Net HP ratings here.
The ZL1 would have to have been about 600 Gross HP to = 505 net HP of the LS7.

Yup.
My belief is that the LS7 has more power and is certainly much lighter and smaller.
Also, please remember that the ZL1 was NEVER intended as a street motor - it would overheat, wouldn't idle, drank gasoline by the tanker load, was sold with the understanding that pulling the exhaust manifolds off and replacing them with headers was more like a "must do" than a "nice idea", etc...

Everybody must have forgot about the 2002 camaro ZL1 with 600 hp and 575tq and yes an all aluminum 427 so the older ZL1 (2002) did have more power :D and it wouldn't be right if they made a new ZL1 with out a 427 in it. thats like a front wheel drive camaro just wrong

That was a GMMG offering, not a factory offering. And they only sold a handful of those cars (69 built). They also came with a hefty price tag. Something like 57k which was more than the c5 z06. A bit too extreme for GM. Leave something like that to GMMG and the other tuners. I'll settle for a cheaper and less extereme 475hp detuned Ls7 or a 485+ hp supercharged ls2 anyday.

the first ZL1 was offered by berger chevy in grand rapids ,mi and only 69 were built then.the 2002 ZL1 was built / offered by berger chevy and gmmg but sold at berger and only 69 were produced with only a handfull being 427 ZL1 and the rest being phase 1 and phase 2 (differant hp rating) so they are still ZL1's and if chevy bring another ZL1 out it better hold up to the ZL1 name 600hp at least!! it's not a ZL1 if it doesn't have a 427 v8 and 600 hp
nothing like making a new ZL1 that gets wasted by the old one!!
i know gm will never make a ZL1 camaro more powerfull than the new z06
so why even make a new ZL1 if it's not going to be true to it's name?
BigBlueCruiser 04-26-2005, 05:34 PM An intercooled SCed LS2 would smoke the LS7 with a pulley and tuning.
I'm not sure if the block can handle it though. The iron mod motor is a hefty SOB, but if GM builds the shortblock right then it's a no brainer.
SC 6.0 for me.

C5R blocks are good for in excess of 1000hp. They're the choice for ultra-high horsepower LSx applications - and aren't even breaking a sweat at 500-700hp. I believe the LS7 IS a C5R/C6R block, plus or minus some relatively minor features.
At the top end of the horsepower spectrum the C5R block is the king of the modern mid-displacement V8 hill, regardless of manufacturer.
Lighter, stronger, smaller.
AronZ28 04-27-2005, 01:04 AM LS7, duh. Racing pedigree with the C5R program. Not to mention it is the most race inspired street motor I've ever seen.
I also want to know who in their right mind voted for the supercharged LS2, and what their reasoning was? That combination should be more slated for a production SS and not an ultra exotic that would be the Z28... er I mean ZL1. ;)
Both would have their advantages IMO.
S/C LS2 would not step of the toes of Z06 owners, and it would beat the Cobra at its own game.
LS7 would be lighter, and be a 427 just like the original.
Both put out about the same stock power so that wouldn't be too much of an issue.
