Default My 1981 Z28 mods & updates.

Over the last month, I have been working on getting my Z28 the way I want it. I started by re-dying the interior, replacing the radio with a full din radio. Then I dug the louvres out of the barn, re-conditioned them and put them back on.
I decided the engine bay needed more work, so I cleaned it up good and then started buying chrome bits and pieces for it. After I got everything on, the car developed a bad miss and I found that the distributor cap and rotor was badly worn. Listed below is all the parts added, replaced, or modified:

-Fender Braces, replaced with Chrome.
-Hood Latch plate, replaced with Chrome.
-Valve Covers, chrome
-Braided hose kit. Stainless ends.
-Corrugated Chrome tubing.
-Fuel hose and filter (due to rupture which is the reason for the fire extinguisher below)
-Engine block and intake, repaint.
-Alternator, repaint
-Compressor, repainted with brush
-Master cylinder and booster re-paint
-Hood insulation
-Factory breather dish, put back on and repainted.
-K&N Filter
-K&N Valve Cover breather
-Windshield base vents repainted.
-MSD Distributor
-Accel Blue Inductor core plug wires
-MSD Multiple Spark Discharge box (in the process of installing).
-MOROSO wire looms.
-Smog Rail delete (damn putting plug wires on with that thing in the way.)
-Fire Extinguisher mounted back seat hump
-Re-dyed upper and lower sail panels, console lid, and t-top trim.



BEFORE.
AS OF SEPT 20

Still have not centered the distributor, plug wires are on. Gotta clean the valve covers up a little.


More pictures to come, once I get the distributor centered and the MSD box installed.

Also, request something you want to see if it is not pictured and I'll try to snap a picture of it real quick.

Seems to be doing really good in the test run, but the idle was really too turbulent to be 100% sure. I couldn't retard the timing enough to smooth it out because the distributor was so far off center, it was hitting the trans dipstick tube.
I just have to realign it with the oil pump and center it.

Its ok. I appreciated it. lol
I'm a liaison between the Camaro forums and the sister Chevrolet Forum, but I help out where needed, I just don't get around to posting much.

Updating on the progress of the ignition swap.. I pulled out my unused sand canister under the windshield fluid reservior and I'm thinking about mounting the Multiple Spark Discharge box in its place.
I had to pull the 4-pin ignition module out of the distributor and replace it with a wiring harness to run to the MSD box. I still have a relay to put in to power it and a killswitch. Then all thats left is to just put the wiring in corrugated tubing and time the ignition.

I had the MSD deal for stock HEI. I liked it. Replaced the coil in the cap with a cover with a stud for a coil wire. Then used a conventional Blaster 2 coil. Still have it actually.

'preciate it bud!

77nomad, thats a pretty good idea, but they make HEI blasters too, so I may eventually get one if the standard MSD coil ever craps on me.


Updating the thread, I got the distributor mostly wired today and took more pictures. I also took some pictures of the killswitch I installed and consequentially also took a picture of the radio I installed. I just have to dig up some wiring connectors and I will be completely finished with the wiring of the ignition system.

I don't know if you drive in the rain but make sure water can't get to your box down there. I power washed mine once. ONCE. Fortunately it was still under warranty. I told them it was on my truck and they assumed I meant mud truck and warrantied it. they sent it back with a list of diodes that blew. LOL
