I'm making rookie mistakes, but at least I know the oil pump works.

Blew oil right past the untightened oil line.  Engine didn't fire - I lost about a pint on the starter motor.

It's mopped up, and I cleaned up the concrete with some lacquer thinner.

No water seepage, and the electric water pump seems to work. 

But it's bed time for Bozo . . .

Here's a great way to kill an hour while updating firmware on an ecu - which is what tonight's all about -

I had to decline the invitation.  Still programming the ecu today.

Setting up the parameters wasn't easy, but i got through it. 

Still won't start, and I'm seeing three problems - One for sure, two potential.

1.  I've got a miss-pin from the output of one of the coil trigger wires.  Need to pull the harness and rewire that.  A ten-minute job, of course - might be able to get it done tonight . . .

B.  The power supply to the coil smoked a fuse - better that than the harness.  Might have been due to the miss-pin.

3.7(y)  An online search confirmed that the trigger output from the Holley HP for the ignition is 5 volts.  My MSD coil packs are triggered by 12 volt, so even if it isn't miss-pinned, it's unlikely the ECU will fire the coils.  The MSD Coils are interfaced with the DIS MSD Interface Modules # 8870.

Digging into it on line, but a few questions, if anybody knows.

I'm looking at the MSD 6302 as a possible solution.  https://www.summitracing.com/parts/msd-6302/recommendedparts

It's a dual coil igniter designed to work with the MSD coil packs, so I think it should receive the 5V signal from the ECU and make the coils to fire.

Anybody know?  Anybody know someone who might know?  :?

So... if I want to emulate a record-setter, I need to number my three problems as 1., B., and 3.7(y)? 8-)

Do you have four 50 watt NPN transistors handy? If so, add a few resistors to build a collector-follower amp for each coil pack- 5v in, 12v out.

It's been a while since I've done any breadboarding, but that's an option.

Good news is that there is NO MISS-PIN.  I had checked this harness many times, and a pin-in to connector-out continuity check this morning verified I have had this right all along.

So that leaves troubleshooting the blown fuse and 3.7(y).

Congratulations to Tom Donney of Fort Dodge, Iowa, and his crew and family.  They bumped the I/GT record today, and while I don't have a definitive number, these folks have busted their humps making their SAAB into a frighteningly fast little 1 liter GT competitor.

I'll post up his speed when USFRA does.

To Tom and crew -

Chris;

A big MOSFET should do what you want. Here is a link to a good candidate:

https://www.mouser.com/ProductDetail/STMicroelectronics/STW56N60M2?qs=sGAEpiMZZMshyDBzk1%2fWi0dsXOGve85xPJUjOcbS6yy2P%2f4CIxNNrw%3d%3d

Its gate threshold voltage is low enough to be driven with a 5V input and its drain current, breakdown voltage and power dissipation make it almost bullet proof. If you have a part number or schematic of your coil-pack I may be able to help you with a circuit.

Is there somebody out there in or near London (England) who might be able to check out a piece of machinery (a Sunnen valve grinder) for me?

Supposedly a machinery dealer in London.   Address is close to Holborn Viaduct & Farringdon Street.

Any help would be appreciated.   Trying to make certain the dealer is not a scammer.

Thanks in advance for any help.  Liquid compensation available . . . . . .   :-D
