I wouldn't do an LS9, as Bob Cosby mentions above, there's so much potential in the existing LS3. For 1/2 of what you would spend on an LS9, you could get a LOT of power from your LS3.

Re the prices - if you can cut out the extra profit padding junk from the package (i.e., going down the list, stop immediately after "Engine Management Calibration"), and pare it down to the real upgrades, maybe it's more reasonable.

Of course, the even better way to go might be to 1) go with Lingenfelter's supercharger or 2) get the Supercharger System (which, based on other Magnuson offerings, would include the fuel system upgrade, an air induction kit, and a flash loader with PCM tuing) from a non Hennessy Magnuson dealer.

 

8 grand at lingenfelter gets you the magnuson intercooled supercharger and all the fuel upgrades and tunning. not bad. and a 3 yr warranty. im really concidering it. their only about 3 1/2 hrs away from me.

 

FWIW (and it isn't much), the latest issue of Car Craft suggests that the Z/28 is back in the plans. (I know, old info most likely, but as long as there is a glimmer of hope...)

 

too late for me. im already on with the ss. i wish it were coming out a little quicker. id buy one for sure.

 

After June 1st I don't think it really matters what was in the plans at GM.

 

I looked a couple of different places yesterday. The consensus was that the block had some reinforcements. The heads are dimensionally the same, but are cast and machined differently. I am not sure if these are perfect sources. I just hit Google and read a few things. I think most of the info came off of Corvette and Cadillac forums.

 

Why? Do you think they're going to stop building cars that will sell well?

Even if GM were to build only 5000 Z/28s, they'd sell every last one before they ever started production.

 

thats very true. i bet if they offered the z28 off the bat in october, 90% of those sold orders would be for the z28. they could easily sell close to 10k of those without anyone seeing or driving it.
