My loss – your gain…..

I’ve got a 92 Z-28 that I have lost interest in, and want out of my life (and garage). It would be a great track car / autocross car, with a little work. Here are the highlights:

92 Z-28 Hardtop Car – 135k on the odo. The paint (teal) is shot, but there is no rust on the car. Glastek Fiberglass Cowl hood (bolt on). Expected dents and dings, but no major bodywork needed.

Engine .020 over 350 – 10.6 – 1 CR, Splayed main caps, steel crank and rods, KB pistons, Aluminum L98 heads, CC-305 cam and SS roller rockers. Holley Stealth Ram intake w/ 52 mm TB, SLP Headers and Cat-back (no cats) Exhaust. I bought the long block from Trackbird, so if there are any questions I can’t answer – he can. (less than 1,500 miles – maybe less than 1,000 – can’t remember the odo when it went in)

T-56 Conversion – Centerforce DF clutch, Pro 5.0 shifter, Spohn Crossmember and TA. (not sure of the total miles, but the gearbox was gone through before installation by Dan Popp of McClusky Chevrolet in Cincinnati)

Rebuilt rearend – 3.73 Motive Gears, Eaton Posi, Moser Axles, Summit Aluminum Cover, Ratech install parts w/ solid pinion spacer (less than 200 miles)

Chassis – Spohn subframe connectors (weld in), Eibach springs, KYB shocks, all new steering parts from spindle to spindle (except Pitman arm)

The engine needs tuned for the cam / intake – I have a number of items from Craig Moates that will be available separately to whoever buys the car. Some of the additional items available are:

Laptop w/ scanning, emulator, and prom burning tools
New C4-HD front brake setup from Ed Miller
Corbeau Seats and brackets (almost new – still in box)
Adjustable LCA’s and Panhard rod – needs new rod ends.
1LE – a/c delete boxes (2) and air pump replacement pulley

I figure I’ve got over $15k into the car plus however many hours (way too many). I’m going to ask $7k OBO for the car (only) and see where that gets me. I’m not going to part out the car of sell any of the extra parts until the car is sold. If anyone has any interest, please PM me or e-mail me at mhalter@columbus.rr.com .

Thanks,

Mike

Jeff, you're really right about that. I built the engine (had a machine shop do the work, but I selected the parts for it) and it's a splayed main cap motor, ZZ3 steel crank, balanced, torque plate honed, deck plugs, 0 decked, etc (I could go on). It was thoroughly and properly done and built from a sub 5k mile "warranty motor" block (tossed the rest) from GM (piston slap). So, it was seasoned, but not even dirty yet.

With the current setup and a proper tune, what kind of power would you expect from it?

It's probably limited by the heads flow potential (ZZ3/ZZ4 heads with Manley race flow valves, skim cut to make sure they were true and 3 angle valve job, etc) to something in the mid to upper 300 (375-ish?) hp. I might be surprised and it may do that at the wheels, but I'd rather guess low. It's truly at 10.6:1 (12cc dished piston, 0 decked, 58cc combustion chamber, that actually seem to measure closer to 56 in real life, then skim cut, it might be a bit over 10.6:1) and the cam is a 220/230 .525 (Crane Compu Cam, those are the specs as I remember, he bought that cam, I was going to use a "street roller" solid roller, but a real small one in it).

The heads (stock) flow about 208 cfm at .600 and about 200 cfm at .500 (as I remember), I put undercut valves in these which should help low lift (area under the curve) and max lift to some extent. I'm not expecting "big things", but it helps. So, you'll be head limited, but with a decent cam (such as what's in it) and that intake, it has potential to make power. It has K-motion K750 (as I remember) springs in it, I think he put Comp Pro Magnum roller rockers on it, ARP main studs, Lunati Street Race rods, Clevite bearings, a Street Damper, all ARP hardware, etc. It was built as a nice street motor that could play at the track. It should live a long and healty life at 400-450 hp, maybe a bit more.
