That would be great but just use the LSX block & DR heads.

I would like to see the Z28 follow the Z06...
LS7 and 6 Speed Only, Maybe without Dry Sump for $ Savings, Aluminum Structure Components, Stiffer Body, Light Weight Wheels and Tires and an Aero Package.
Offer a Limited Production Radio, AC, Sound Dedening and Rear Seat Delete Package and a Track Package with Differential and Gearing Changes along with better Brakes and Light Weight Front Seats.

Maybe 200 Lbs weight savings is a lot to ask and still be affordable, but 100-125 lbs isn't unrealistic and if you had a limited production option that could save 200-250 lbs, people would buy it.

Then just keep things simple and tune the suspension to handle the road course and move all the weight effectively.

I could see how it would be cheaper to produce a modified LS7 without dry sump and give it a new name than develope an entirely new motor.

If you already have a new engine series under development does it warrant validating a old engine for a new configuration just to release a Z/28, or does it make since to wait for the new engine?????

iron block = extra nose weight = bad for handling

Sure, but the thing that makes a Z28 a Z28 (or at least what should make a Z28 a Z28) is its handling, not its potential for power adders.

Well I know this, back in the 60s when they came out. At The local hang outs, they were used as drag racing, and street racing cars. You never saw locals use them for road racing, or their handling. They were some bad little cars, on the street back in the day.

Not exactly 100% true. Yes the Z/28 was the best handling package Camaro from the factory. BUT the Z/28 was a parts bin car, it was the best handling selected pieces from the Camaro option list and put into a package. All the pieces for the suspension could be option on to any Camaro in 1967 - 1969, so yes you could build a SS350 Camaro that on street would have run the wheels off a Z/28, the 350 had torque the 302 could not match in stock form. A prepped Z/28 would kill an SS350 Camaro but off the showroom floor a SS350 could be option to hurt the Z. Big Block ZL1 would have had too much torque to control in handling with the tires available, the iron block 396 and 427 was just too damn nose heavy to even come close to a Z/28 even with the same suspension.

So, if some use their Z28 as a daily commuter, it should therefore get packed with comfort options, have a nice soft suspension, and get excellent fuel economy?

Having been there back in the day, I can assure you that I never saw a SS350 Camaro that could "run the wheels off a Z/28"!! I'm not talking about "you could build" or "prepped", I'm talking about how almost all of them came from the factory. How many people ever ordered a '67-'69 SS with anything but the basic suspension package? You also seem to forget that while the SS350 came with 14" wheels and tires, the Z/28 came with 15" but still sat lower than the SS versions. And the SS 350 engine had hydraulic lifters with a 5,500 RPM redline, the Z/28 302 had solid lifters with a 6,500-7,000 RPM redline. SS 350 was rated at 295HP (300HP in '69) at 4,800 RPM and 380 lb./ft. torque at 3,200 RPM, Z/28 302 was rated 290HP at 5,800 RPM and 290 lb./ft. torque at 4,200 RPM, higher RPMs gave much better figures than the factory ratings for the Z/28 302, 350HP at 6,700 RPM and 333 lb./ft. torque at 4,400RPM. What you often saw was a SS350 getting the jump off the line only to lose to the Z/28 farther down the road once the Z/28 was staying within it's optimal RPM range. And again, most SS Camaros back then did not have anything "extra" ordered in the suspension components and a quick cruise through the "twisties" would confirm that. I totally agree with your conclusions about the iron block 396 and 427 engines being too nose heavy, conclusions about ZL1 handling back then are subject to speculation as most of them were bought as 1320 stormers and nothing else. In the end, I believe we need to focus on what GM might give us if and when they build a new Z/28.

You're also talking about a car that will get its ass kicked in the twisties

How true, and many times I was the one in my Z/28 going past them somewhere during the last 400 feet. Big Blocks that wouldn't run consistently were beaten as well on occasion. That 302 really did have the ability to breathe at high revs for the time period it was in. Having said that, there were plenty of cars back then that I couldn't run down if I had to.
Put plain and simple, the 1st gen Z/28s were quality high performance cars that were tons of fun to drive AND at a price point within reach of a large part of the population.

I for one think they are waiting for a new engine if/when they bring back a Z28.

So true. But for every 1. Z/28 you will see in the twisties, you will see 2 or 3 to 1. more on the streets, or the dragstrip. The old Zs, although they were meant for the twisties. Saw more action on the local streets & the dragstrips, than they did in the twisties. I know because the local hang out, had them out every weekend looking for action.
