Another fantasy poll?

GM already makes a ZL1 crate engine based on the original zl1 block, http://www.sdpc2000.com/catalog/120/...ate-Engine.htm
I vote we use that

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 .

Jackal

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

i am all about the NA LS7

I'm all about a ZL1 camaro...

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 . hehe.

But the Ls7 would be my engine of choice. Just something about having 427 cubes under the hood. 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.

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

FI > NA


EDIT: For some reason my post was Fi > Na... don't know why Fi would be greater than sodium

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.

The LS7 crate motor is what half the price?

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.

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.

the old zl1 had more power than 505hp so the new one should. i say do the iron 572 (like Moss's aluminum 572).
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?
