🔥 ACDelco D447 Ignition Distributor Rotor: GM Original Equipment in White - High-Quality Performance Review

Great! Installed in a 1995 GMC Sierra K1500 - a perfect fit, the AC Delco is a great choice. My truck idles smoothly and starts quickly. I'm glad these parts are still available. Many Thanks

I had no other expectations than this rotor would fit my stock Chevy 350 manifold, which it did. My old one was badly worn so I was hoping that a new one (and/or a new cap, wires and spark plugs) would improve my performance or fuel economy, but it made no difference. There's little you can do to save fuel when you're running a 6-inch lifter and 33-inch tires on a boxy Suburban. At least it drives great.

At just under $6, it was reasonably priced and a perfect fit. I probably didn't need it, but since I replaced the spark plug wires and distributor cap, it seemed like spending a few extra bucks for an item that would transfer the spark from one to the other would be a no-brainer. I've always had good luck with AC Delco parts, and for my 1990 Chevy K2500 pickup, Revain's compatibility guide has never let me down. The rotor appears to be OE quality and the price is right so it gets 5 stars.

The upper parts of the rotor that they are fitted to often rust, making for a tight fit. This knot is a bit tight even after cleaning and grinding. Some brands use a looser tolerance for this, but they don't, so I placed an old rotor knob upside down over this one (like a gasket screwdriver) and tapped it lightly with a rubber mallet. This snapped it into place, but it took a little patience, but the sloppy fit with plastic welding (to hold the slightly curved center tongue) wasn't what I…

I bought this to add a cheap foreign made manifold system to a 1992 Chevy Suburban 1550 with a 5.7 liter V8 engine. This rotor is made in the USA and has shown great results when installed in place of the cheap rotor that comes with the distributor. Trust me, I've worked on vintage GM cars my entire life, including muscle cars from the '60s and '70s. It's getting hard to find really high-performing electronic engine parts at dealerships these days. I used to buy GM HEI blueprints from Accel…
