ZL1-LSA-MR+LS7+Pedders Coilovers = Z28?

[Q-ship]

Thinner glass would require crash recertification, the windshield and rear glass is part of the structure of the vehicles nowadays. Side glass I can not speak too. There is more to adding the LS7 than just dropping it in the Camaro like people have said, it will require new emission and fuel standard tests......it WILL require those test not may. The OEMs have to meet stardards that none of most here understand or comprehend, just cause you can bolt in an LS7, Pedder suspension, and a louder exhaust does not mean GM can that easy! The LS7 is a HAND built engine not the production line piece like the LS3 is, higher volume will not see cost returns everyone thinks. Of course a retuned LS3 will need to be recertified too (but it could be done on a regular production line and not hand built), this why it is so hard for the OEMs to come out with these cars today. We don't know how long Ford worked on and what the cost was the bring the Boss to light of day.

I would:

1. Reduce sound deadener
2. Retune the LS3 for 450hp much like Ford did to the 5.0 in the Boss
3. Better seats that are lighter (Recaros is a factory seat in other OEMs)
4. LOOSE the big heavy blingy wagon wheels (18's will fit, and the need for ZL1 brakes goes away, forget the ZL1 heavy a$$ 20" too they are wrong for a handling car)
5. Gearing (3.70?)
6. Decontent the Z/28 in standard forum, allow costumers to add to weighty stuff back if they choose too.
7. A tastefull body kit and front splitter (a serious challenge today....the ZL1/Bumblebee nose is UGLY!!! IMO)
8. Retune the suspension (swaybars, springs, and shocks) By the way Pedder is not the end all be all suspension kit out there.

Adding HP to keep up with the Boss in a handling car is like "Screwing for virginity", weight is a bigger deal in a car that handles than even a drag car.

Now you either have to mod your car to accept the dry sump system and buy the dry sump system, or you have to adapt the LS7 to work without one, which I've never seen done before. Either way, it's not going to be cheap.

Another thing that the LSA has over the LS7 is about 80 Lbs Ft of torque.

Don't get me wrong, I love the LS7! It's a great engine! If they put one in the Z28, it would be cool, but I'd still buy a ZL1.

Earlier, in this thread and others, mention has been made of "wet-sump LS7". The dry-sump tank suffers from packaging issues in the Camaro, and does NOT pass any sort of crash test when "front-end mounted", the simplest refit seen thus far... Great for "aftermarket", not so for OEM.

Wet-sump'd, the LS7 vs. LS3 weight issue...isn't. An LS7'd Z/28 will weigh virtually the same as a 1SS before being "Z-ified"...

The avoidance of the LSA is to get away from the 150 extra lbs. on the nose...the bugaboo that necessitates the MR suspension on the ZL1 which, by itself, adds further weight... ZL1s will Curb greater than 4,000 lbs.

EDIT: Q-ship's "Q-ship" Z would price out under $40Gs...or should...and IF there's a Z/28, no way will it undercut the BOSS's pricepoint. So what more needs to be added/changed/deleted?

Weight OK, they make the Z28 LSA blower, heads and block out of titanium to get back to LS3 weight. Money Where are we with the engine choice

Cool! I missed that! Too much thread and not enough time! That certainly would make hot rodding with the LS7 a lot easier.

Driving in a Z06 is a blast! I'm all for it! That's where the LS7 belongs!

Weight, throttle control, & heat soak.

[JusticePete]

The crate engines available from GMPP do not talk to the OE computers. They do not support gauge function. This is by design and government regulation.

Heat soak, yech! We are talking massive coolers (oil and PS) for a Z28 and a dif cooler.

[LOWDOWN]

Engine choice, Pete? I'm stickin' with the LS7...

Built in these volumes (5000 or so), that's 5 TIMES the Z06. Contrary to other opinion, and even if "hand-built", unit co$t$ MUST be decreased...more blocks/heads/ti rods/cranks etc. And yes, there is some validation work to be done. But the vast majority of development has already been accrued, and can now be amortized over far more units, for whatever duration the LS7 remains (likely through balance of current-Gen Vette, approaching the next-Gen Camaro and therefore next-Gen engines). Compare the expendiency and costs to validating FOR PRODUCTION PURPOSES a "hot" LS3 (there IS a difference between Parts criteria and Production criteria, and the revised LS3 would have to be smog'd, which it currently isn't...LS7 is). Again, more torque (not inconsequential in a car of this size, regardless of its final Curb), more power more easily, more rev-able, and, at this unit size, not much (if any) more expensive at source.

If an LS7 CAN be made available, "within pricing/cost constraints", why wouldn't we want it?

BTW, Scoggin-Dickey sells a MAST-built LS3-based 427 with Eagle internals for $16,995. Makes 600hp. They ALSO sell a similarly-constructed and -pieced LS7-based 427 for the SAME PRICE. Power from the LS7 version? 650hp ...same price, same displacement, similar componenets! So which engine is the basis for greater potential?

Maybe the key to the Z28 is pre-orders. Say 5,000 pre-sold with non-refundable $5K deposits. Lock down the build sheet and limit the colors. They parade down the assembly line in an incredibly efficient process.

600 NA would make for an extraordinary Z28. Combine that kind of HP / TQ with new tranny and rear end gears... MONSTER Z28

Would it be tough to get that power to the ground? Seems like we are getting in to the area that slicks or really good sport tires are going to be needed at the track.

I'm not suggesting, or expecting, 600+...it was intended as a comparison between LS3 blocks 'n stuff vs. LS7. LS3 is stouT...LS7 is REAL STOUT!

Streamlined, and/or "batch-built"...certainly easier for the CAW to sign up for!

BTW, I erred in my S-D pricing...the difference is actually $3,000 in favor of the '3...sorry. Which, all other things considered, is likely what the difference should be based on the recipes we are likely to see from GM. Personally, I'd pay $3Gs more for the LS7-Z/28 combo...50 warranted horsepower, that still has another 50 left for "tuning", is a pretty nice place to be for that lil difference!

Coming out of GM it would probably have 305/30/20s in the rear. That would be sufficient. If I had my choice we would be talking about a Z28 with a square setup 305/30/19s all around. With a boosted 600 like the Pedders Camaro powering out of the corners took a very measured throttle to control the boost coming on. With an NA setup it would be freaking sick to drive. I am thinking about canceling my ZL1 for the Z28 being built here.

I would be willing to bet that with 600 HP there would be quite a few people out driving their skill level realllll quick

The Z28 that is being built in here sounds pretty sweet to me. I guess we will have to wait and see if GM can make a case for it!

Maybe they will suprise us with a 5th GEN DI-V8..... what I can wish cant I???????

Pete, that's the LAST thing GM wants to see in print!!! That's exactly why you'll not see any announcement (if there ever is one...) about a Z/28 till after ALL the '12 ZL1s are spoken for AND likely delivered...

Sadly...this recipe was good-to-go 18 months ago...but a suitable "fleet" of Camaros was not made available...and then Daddy BigBuck$ took his bat 'n ball home...

However, the price might have been a tad more than $45...

Pete, don't say that. Chevrolet maybe concerned about the "THUNDER STEALING" Z/28.
