Hi guys, I'm back! The Z28tt sat for 8 years as my hobbies shifted away from race cars (to cycling and flying...). Anyways, with COVID work from home, I had more time (and couldn't sleep well), so I started working on the Camaro again. Drained the oil, first gallon was coolant! Replaced the intake manifold gasket with a new one, and also replaced the fuel pump with an Aeromotive 340 (original was making bad noises). Replaced plugs, ultrasonically attempted to "clean" the injectors with a pulser and the Harbor Freight cleaner. Replaced mice chewed wires, etc... Finally got it running, registered in a new state, and got classic plates (Jeez, this was my first car and was only 6 years old at the time!). Man those hard, old tires make driving sideways fun
I picked up an Emtron KV8 ECU, so the next phase is getting sequential injection setup, and ultimately drive by wire.
Here's this morning's progress from machining the 60-2 crank trigger pattern into the crank pulley. First time using the compound rotary table. Glad I got it with the Bridgeport! Holes are .1875" with a .300 depth, close to a 50% pulsewidth, on about a 7.5" bolt circle (8.5" pulley). I wanted to use a 4 flute flat bottom end mill, but it wasn't long enough to clear, so I used a drill instead. Bosch VR sensors have a 3.5mm (.138") diameter pole. I read somewhere that the tooth width should be the same as the pole, but these are a bit larger. We'll see what the signal looks like. Halfway there!

afgun,
The Bridgeport was a “signing” bonus when I went to work at Mallory Billet Aluminum (more like Mallory Industries, the aeromotive side). I see them pretty frequently on classifieds, $1-$2k for the basic ones. I had to put on a variable frequency drive to power the 3 phase motor from my single phase house (wasn’t too expensive), and then I added the digital read out after I scrapped some parts when I mis-counted a revolution on the dial. It’s nice to have if you have the space. You can pretty much make anything with it! I gave my drill press to my neighbor.
Orr-I have a set on my car too!
It’s fun getting back into it. A lot has changed in some ways, and not in others. This year is getting the car sorted, and next year I’ll make it look nice.

I've been following on a couple of FB groups you've been posting... I'm in much the same boat with my '87 (my '83 from back then was totaled during hurricane Isabel in 2003 when it dropped an 8' in diameter oak tree on it), also aeromotive 340, also coolant, I found an intake port full of coolant and traced it down to a crack in an intake port valve bowl that is leaking coolant and I haven't quite figured out how to weld it yet.

Why did you go Emtron?
I have 2 megasquirts and a microsquirt sitting around so right now mine is getting a MS

So you decided 60-2 (I saw your debate about that). Lately, I've been burned repeatedly with the "more resolution" thing on my projects. Most recently I figured out that my home built 3d printer was getting some weird artifacts because it was studdering at higher speeds and it turned out that the processor couldn't keep up with the resolution, when I decreased that everything went smooth and good.
Of course, I have no idea of the Emtron's capabilities...

LOL, my drill press got dedicated to mostly woodworking in the basement, the BP is in the garage. Of course, I've actually figured out that my 2300# BP has caused my garage slab to sink about 1" in that corner. DRO's are a godsend on old clapped-out BP's, Mine came with one, but the PO installed the travel stops on the wrong side and I ended up destroying the Y-axis glass scale at using the full travel of the table milling a cylinder head. It turned out it was cheaper to replace install a whole modern DRO with 3 axis than just replace the Mitutoyo scale.
