I scored a Mallory Hyfire 6a as part of a transmission buy.  it's new in box, never installed and I was thinking about installing it on the Thunderbird.  The 292 is mostly stock except for Mummert intake, Holley 450, Sanderson headers, Mallory Unilite distributor and Mallory coil.  Stock type plug wires that are only a few thousand miles old.

Anyway, any thoughts on whether it's worth installing?  Online searches make me think it might be just one more thing to go wrong , but it might be an improvement also.  I figure I'll have to change plug wires again, but anything else?
