Mallory Dizzy?

Looks good to me. I know some law enforcement agencies have used
Mallory ignition componets, so I'd imagine they make good stuff.
Plus, I haven't heard any horror stories about them (MSD= might suddenly die).

IMHO an aftermarket dizzy won't show much gain if at all over the stock unit, since they both use a not-so-great Hall-effect sensor design (magnetic pickup) which does not produce a perfect square wave pattern like an optical pickup would. I certainly wouldn't pay 2-3 times the price of a reman just because its shinier and uses a bearing instead of a bushing. The bushing in my stock one lasted almost 200,000kms. Stock replacement is more than adequate.
The only trick here is that reman units don't always have new PIP sensors in them, because they test them before disassembly, and if they still work correctly they are re-used. Have a good close look at it before you buy it.
