Real-World Testing: Putting Sierra International 185479 Flame Thrower Electronic Distributor For Gm Sb & Bb V8 Engines With Standard Deck Height to the Test
First Use Experience
I installed the Sierra International 185479 Flame Thrower Electronic Distributor on a 350 cubic inch small block Chevy V8 in a classic speedboat, which I restored. The boat operates in a demanding marine environment, where reliability and performance are paramount. Installation was straightforward, leveraging the distributor’s drop-in design, though aligning the timing required some patience and a timing light. The engine immediately started smoother and idled more consistently compared to the old points system.
The true test came during an extended run on the water, where the engine performed flawlessly. The distributor held its timing steady, even under varying loads and RPMs, a stark contrast to the drifting timing I experienced with the old points system. There were no hiccups or misfires, even after sustained high-speed runs through choppy water.
Extended Use & Reliability
After a full season of boating, the Sierra International 185479 has proven its reliability and durability. It has logged over 100 hours of use. There are no signs of wear or corrosion despite the harsh marine environment. Regular checks show the distributor cap and rotor remain in excellent condition, and the timing continues to hold steady.
Maintaining the distributor has been minimal, primarily involving occasional cleaning of the cap and rotor. Compared to the constant adjustments and maintenance required by the points system, this has been a significant time-saver. My previous experiences with electronic ignition systems were mixed, but this Sierra International distributor has exceeded expectations. It offers improved performance and peace of mind compared to traditional ignition setups.
