Yep, we need a functional heat extractor hood on our Z/28 along with ambient air feed. I am not looking for ram air or anything like that, but a true external air feed. I wonder if GM would consider coating the inside and outside of the cast exhuast manifolds to help control under hood temps with our LS7?

I prefer an NA car for a track car. period. as for the LS7. . .I don't want it. with the proper tune it would be fine but knowing my luck I'd do something and then have it blow up in my face. ie my 98 camaro leaned out and threw a rod. at least it ran a 12.5002 at 111.9 before it blew. no power adders.

The TT-LS6 used ACP's carbon fiber World Challenge double vented hood...STILL an issue for it. Heat wrapped everything in sight...STILL an issue...double-coated headers/exhaust...STILL an issue...on a 75 degree day! Desert SouthWest? Forget it...Firebird, Laguna Seca, LVMS...you'd think the thing would MELT! Easy 100 hp drop-off...

Current Z06 vs. potential Z/28...and I predict 10,000+ LS7 ZEEs (which is several times current Z06 volume). Ford is "constrained" (their word) to a total of less than 5,000...4,000 "Base" and 750 LSs, according to "plan".

BTW, 1969 ZEE sales totalled 20,302 units. '69 BOSS 302 = less than 2,000...'70 BOSS 302 = 7,000

"If you build it, they will come..."
10,000 would be a reasonable volume (opinion) out of Wixom, espcially considering the current Corvette volume :(

Heat is a HP killer...........and ultimately and engine killer.

Might have to add employees. That should push the unemployment % in the right direction. So building the Z28 is obviously the right thing to do.

It is less, but far from ZERO.

I was afraid of that



It's just a low volume hand built engine. I don't know the plans on this one, but as long as the engine is emissions compliant or the year, not sure why they couldn't continue.

I thought it was stated that the LS7 was near the end of its life cycle? Probably just a rumor I read.... oops... my bad


Keep looking

Oh I will.... I really want a Z/28. Just trying to figure out if the business case supports a LS7 or not



It depends. If you change ride height you would have to re do side impact testing as just one example as that would position the occupant lower than what you previously tested to.

Well I would assume the Z/28 would be lower than a SS.... Soooo more validation costs there... booooo


Like I said above, it depends on what you do. Bigger wheels with smaller rim to ground clearance need to be looked at even if you maintain ride height. Change ride height and you have to confirm a bunch of other things.

As we often say, the devil is in the details.

I dont work for GM but Im really not liking all the details yall have to go buy

I am learning a lot though.....

Not the best conditions for testing eh? Should have just moved to yuma.... at least then you would be close to the proving grounds!

Why do you keep adding to the cost of our Z/28.......

YeZ love iZ blind!

Yes, Anything I can do to push the idea of a 5Gen Z28 into the realm of possibility I'll continue to do it. I'm trying to be as reasonable as warranted, but I want one!

It just occurred to me there is HISTORICAL PRECEDENCE for Camaro receiving a mass-marketed engine ahead of Corvette. Anyone remember?

Yup...1967, the Camaro's inaugural year. The soon-to-be mass-marketed engine? The 350. Fully TWO MODEL YEARS ahead of Corvette.

GEN-5 V8 Camaro-bound?

Z/28-bound?

Stay tuned...
