1996 mercuriser 454. i want to change to a Mallory dist one piece set up.
Nothing but trouble with thunderbolt.
I hear you on that one!
The Merc TB is EST w/ photo eye triggering.
i have mallorys in my 5.7 merccrusier work fine.
The Mallory of my choice would be the YLM 624 AV.
The YLM series uses the tried and proven VR (variable reluctor) triggering.
The YLU uses photo eye.
Neither of these are EST.
I heard Mallory sold to another co.
"MSD announced on January 4, 2015, that they had acquired the Accel Performance Group, which included Mallory, Mr. Gasket, Lakewood, Quicktime, and Hays, and this move aims to solidify the company's ignition products under one brand, while continuing to provide service for legacy customers."
Has anybody used any of the other brands?
I would steer clear of any ignition system that use the Pertronix style Hall Effect triggering.
Looking for around 300.00 to 400.00 $
