Fitech, Holley Sniper, what is the expected life span

[Willard]

So I was thinking of this and rather than clog up the Sniper or Fitech threads, I will post the question here.

Knowing the other mainstream options out there (AFI, Howell) use rebuilt GM TBI units that are known to run at least 100K or more when they were new.

The Sniper and Fitech EFI units what is the expected life span of this unit? I ask simply as the computer and fuel injectors are all built in and not easily accessible.
The Sniper uses an unknown fuel injector and the Fitech uses supposedly GM injectors from what I have been researching.

Our installs sit right over the exhaust manifold on a 2F and as we all know heat kills wiring, computers etc. While both have said this is not a problem, I still have concerns.

If I or anyone else is thinking of EFI and going to drop 1K+ on this, I would want mine to last for as long as possible.

Any thoughts?

If you're a true DIYer and you want to know what your system is doing, how to fix it, diagnose it, and replace with the parts you want - consider Megasquirt. It's less expensive and you use the parts you want. The learning curve is far greater at the beginning but you get far more control and transparency.

In other applications I have seen heat shields. It would not be a bad idea to make a heat shield out of some stainless steel sheet. Bent in a 90 degree shape over the exhaust side, using the studs and bolts to hold it.

But remember this EFI installed on top of a big V8, in a hot rods per say is not a cool location. Even though the exhaust is there on a 2F, on a 350 or so they get stinking hot. Good airflow is important from the fan to keep the engine bay cool.

This is a good point.
My old Chevelle with long tube headers was not cool by any means when you opened the hood.

I like the heat shield idea a lot. This may be an option for sure.
