IMO mounting the ECU on the engine is asking for problems. The 2 things those ECUs do not like is heat and vibration and putting them on the engine is providing both in abundance. Yes it hides the ECU well but makes replacement a little more difficult, however I think what you gain in cool points in not being able to see it is not worth the shortening of its life by subjecting it to more heat and vibration. You would be better served lengthening the wires and putting it inside the car under the dash if seeing it is a problem.
But hey, if it works for you then so be it.

How much hotter do you think it is on the back of the valley pan versus the firewall on a hot summer day driving your car around with the hood sealed on a 71 Superbee without the ramcharger hood
I can answer that question for you when I was tracing my 5,000 RPMs and above erratic issues this past summer with a laser thermometer that I carried in the car
Now the vibration part - Well obviously that makes sense
Anyways The problem with these aftermarket factory ECUs ignition modules is the country they are made in today and within the past 20 years

Touching the transistor case while in operation will result in a shock....due to the coils collapsing primary winding current that produces the spark in the first place. The transistor and related internal components are designed to harmless dissipate this voltsge. The transistor is a power Darlington design with an internal suppression network. Its NOT the steady state current the transistor handles to charge the coils PRIMARY, but the induced voltage that appears when the transistor turns OFF to produce the spark...identical to a points ignition system operates when the points OPEN.

I mounted mine on the inside of the firewall up under the dash. I stuck some special gasket material to the firewall behind it it as well as stood it off the firewall a 1/2 inch or so to keep it isolated from engine bay heat (the firewall sheetmetal gets warm, even on the inside).

I hide mine on top of passenger side forward frame rail, under the horns. Then I run the wiring harness alongside the alternator harness up to the big block distributor and coil. It is practically invisible.

Lots of great suggestions! Many good alternate places to relocate the ecu. Thanks!
Another thing that strikes me as a bad place to mount something is, on my old 1993 dodge 4x4 Dakota . They mounted the ignition coil on the passenger side exhaust manifold! WTF!
