FAST ignition box - 6000-6400

[SBC-68-FIREBIRD]

Hi Guys,
I currently have an old Crane HI6 on my car which I have had for 20 years. It still works great but the rev limiter no longer works properly. Crane products now go under the brand FAST.

Have any of you used this brand or this particular box & have any feedback on it ?

Thanks.
Scott.

Solid wire plug wires or a bad resistor/suppression plug wire will cause a rev limiter to be erratic.
