Yes, it is an 1/8 mile strip.

RT: 0.621
60: 2.177
330: 5.645
1/8: 8.487
MPH: 87.70
1000: 10.906
1/4: 12.945
MPH: 112.04

Obviously, I took it easy on the launch so I didn't break an axle twice as far from home base as I was at Sumerduck.
+6 MPH vs. the first engine's best trap speed... power's definitely there. I think some of that comes from the 1.02 vs. 0.94 fourth gear, as I wouldn't have expected a <2 mph advantage at the 1/8 to turn into a 6 mph advantage in the 1/4.

MIR was bat **** insane Sunday... There was a swap meet as well as one of the last test/tune days of the season. I didn't make it there as early as I would have liked. I only made two runs, but missed 2nd gear in my second run, so it wasn't any good. If I had gotten there right as the gates opened and gotten set up, I could have had 3 runs by mid-afternoon... but missed the first two sessions in which the groups were not as heavily populated as they were later.

Tech initially gave me guff about my cracked 1/4 windows, so I had to rip those off before they'd let me run. I need to remove them anyway in order to install the replacements, so I don't consider it a big deal. I'm not sure if the car looks more or less ghetto now.

There was a blown nitro funny car that made a couple of runs... 6.20 @ 234 was the faster of the two. If you've never seen A blown nitro car run, go see one. It's a rare treat, like seeing an F-14 do an aerobatic display at an air show... And like the F-14, the nitro car makes the ground shake.

Made some exhaust hangers/braces/handcuffs

Hey Will, are those welded on with a MIG welding machine?

I love the quality finish.

A welder my dad works with TIG'd them. All stainless.

Been driving and enjoying the car... getting together materials and info to build the wiring harness adapter which will let me switch over to the Shelby PCM.

I have everything I need but time.

I have an EP LSD built in the later model larger 282 diff. It's been on the shelf for a while. I shipped it back to Jeff for disassembly.

I'll be sending the components off for cryo and WPC (micro shot-peen/micro-polish) treatment along with my 3.94 R&P and a couple of extra IMS's and male CV joint cups and a new crankshaft for the Northstar.
Once the driveline components have been cryo'd and WPC'd, and the crank cryo'd, melonited, journals cut and micropolished, I'll pull the car down to swap out the crank, install the 3.94 FD and diff and a few other things.
One of the other things will be to remove the chassis side dogbone mount stamping from my wrecked blue '87 GT and install it in The Mule. I had pre-emptively cut The Mule's for clearance to the Northstar cam cover, but once the engine was installed, found that it would have cleared with only minor trimming. I will build a rod-end dogbone from the chassis side mount to a bracket I will build from the Northstar PS pump bracket. I'm thinking that the "springiness" of my urethane powertrain mounts is a contributing factor to the wheel hop that killed my CV joint.

I haven't read your thread beginning to end but I have skimmed here and there. I assume from what I have quoted here that someone actually has a workable Shelby ECM my question is, c an it be made to run 2k+ motor with coil on plug? I'm at the very early stages of attempting to reassemble a very low mileage N* that had some piston damage due to poor tuning on a Microsquirt and high revving. I would love t eventually get it running its COP setup.

I'm the test case. I've been working with Sinister to develop the tune and get the wiring info.

The Shelby computer will not control the Y2K Northstar, as it depends on the DIS brick for the 24x and 4x signals.

There really isn't much you can do for the engine management of the '00-'04 engines... Tuning is actually a serious handicap for those engines.
My advice--especially considering you're just getting started--is to get an '05+ engine. The '05+ *should* be compatible with a WIDE variety of computers, as it used a 58x trigger wheel.

The '93-'99 engines have multiple engine management options are available, but they REQUIRE timeserting the head bolt threads in order to be reliable. That's $500 between the gaskets and the time sert kit... just to put it back to stock.
My understanding is that the '05+ engine are more reliable in that regard, as GM made changes to the depth and pitch of the head bolt threads in those engines. They also have larger exhaust valves than the '00-'04 engines and breathe a little better.


www.car-parts.com shows that Standard Auto Wreckers in Ontario has about 5 '06-'08 engines for $1K each. There's an LKQ yard in London that has one for $900. Diamond Auto Parts in Mississauga has an '05 VIN 9 for $900.

Edit: After looking at a map, I see you're not far from Detroit... you shouldn't have ANY problem finding an '05+ Northstar for cheap.

I'm not sure what search criteria you're using Will but when I search for *engine 2005-2008 Cadillac Seville* I get a half dozen N* in Michigan all for $1500.00
Will DEC 21, 10:14 PM
Try DeVille for '05 or DTS for '06+... That was the only Northstar car that stayed FWD through the end of production.
