Review: New life to old engines - I'm not a gear head. Don't have a shop full of once-in-a-blue moon tools. I can change my plugs and fiddle with my carb- that's about it. But I have a 70' Ford F-100 with a 360 engine and I love my truck...way more than mechanical knowledge can express. Luckily, some awesome nerds got together some time ago and figured out a way to implement more modern firing and timing systems into the existing distributor. My experience with this product came as result of nearly having my ears blown off when my truck backfired. Everyone in the neighborhood ducked, getting up slowly to look around. I knew something was up before this happened. My truck had been having very rough acceleration. I thought/hoped it was my carb (cause I can mess with that). After some fiddling and the neighbors ducking a couple more times I finally found a mechanic who would answer my questions- turned out...duh, my points are off. Now I grew up with cars that were quiet and smooth and didn't have any of this points business. So naturally...I had no idea how to change them...or honestly how they worked. But I do know how to do math. My points were last set about a year and a half ago. It cost me about [...] bucks. I had seen the pertronix products in the LMC trucks catalogs. I figure if they improve my fuel economy/horsepower and give me smoother and more even acceleration response AND I can skip the trip to the mechanic every year then why not try them out. I also bought the flame thrower II (it's recommended). Total cost $[...]. Install was really easy, although the instructions could have used some more diagrams and to have been a little more comprehensive/thorough. I guess they figure everyone who buys these products knows every inch of their truck...well not me and I wasted valuable minutes of my life pondering a few phrases. The only weird thing to watch in my particular install was that the starter wire goes on the left of the ignition coil now instead of the right. I already had premium bosch spark plugs...if you don't I highly recommend them. Also if you install this product you can play with your carb to make the mix a little leaner/thicker if you want. I would also adjust the idle while you're at it...my idle rpms jumped substantially from the added punch and precise timing. The end result has been fantastic. I feel like I have a brand new truck. It's so responsive through the whole rpm cycle. Reduced vibration. Improved fuel economy (very slight). But the performance is a huge improvement. I wish I had done this when I first bought my truck three years ago. Most people know some of the best money spent in improving a vehicle is done in the firing chain. This product is perfect example of that. It's given me the best driving experience my truck has likely offered in decades. Best of all my neighbors no longer cowar in fear when I drive by but instead wave and smile. Review: great product - I installed this on my 1970 Ford Galaxie with a 390 along with the Ignitor II Flame Thrower Coil (.6 ohm) and the Flame Thrower custom fit 7mm spark plug wires. The installation took less than half and hour and the car fired right up when I first started it. I checked the timing advance and it was spot on, 10 degrees BTDC with 36 degrees total advance. This model has adaptive dwell control, I checked it with my dwell meter and found that it was doing what it said, from 14 initial to about 23 at high rpm. I recommend this product! ## Features - ENHANCED IGNITION PERFORMANCE: Experience superior starting voltage and adaptive dwell control with the Pertronix electronic ignition conversion kit; This Ignitor II maintains a stock look while significantly improving ignition system performance - VERSATILE APPLICATION COVERAGE: This ignition kit is designed to fit most distributors originally equipped with mechanical breaker points; This kit is suitable for a wide range of automotive, marine, industrial, and agriculture applications - INCREASED ENERGY OUTPUT: Benefit from up to 4 times more available energy between 3000 and 5000 RPM, and 2 times more available plug voltage; The adaptive dwell technology maintains peak energy throughout the entire RPM range - IMPROVED TIMING AND EFFICIENCY: Experience enhanced timing accuracy and prevention of 'points bounce' at higher RPMs; The Ignitor II electronic ignition kit compensates for electronic delay by adjusting spark timing across all RPM ranges - QUICK START: Sense startup conditions and develop more energy for faster starting; Pair with a Flame Thrower Canister Coil for optimal performance; This maintenance-free electronic ignition system eliminates the need for regular point replacements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000JUT7RS | | Best Sellers Rank | #192,313 in Automotive ( See Top 100 in Automotive ) #5 in Automotive Performance Igniters | | Brand | Pertronix | | Customer Reviews | 4.6 4.6 out of 5 stars (213) | | Date First Available | September 14, 2004 | | Exterior | Machined | | Is Discontinued By Manufacturer | No | | Item Weight | 3.2 ounces | | Item model number | 91281 | | Manufacturer | Pertronix | | Manufacturer Part Number | 91281 | | Model | Ignitor II | | OEM Part Number | 91281 | | Product Dimensions | 6 x 4.8 x 4.8 inches | ## Images ![91281 Ignitor II Electronic Ignition Conversion Kit, Compatible with Ford 8 Cylinder, Adaptive Dwell Control, Black - Image 1](https://m.media-amazon.com/images/I/517mCQzbpDL.jpg) ## Questions & Answers **Q: Will this work on a 1966 with the 352?** A: Yes, I use one on a 390 in a 63. The 352 & 390 are in the same engine family. I would suggest using the basic version of the PerTronix. The PreTronix is very easy to install if you have any electrical skills and it is much simpler than points. I did notice that the rpms would fluctuate during idle. I used the Ignitor 1 on a 289 and worked very well. Either version you use should be a great improvement over the old points set up. **Q: Is this compatible with a 65 tbird 390 engine?** A: Please check with Pertronix. Call 800-827-3758 | 909-599-5955 . Great people to work with **Q: The igniter 2 module im replacing has a numbero2y-ai2b on the white sticker on the module. which igniter 2 do i need to buy to replace it?** A: Not sure what the numbers mean. Go to the Pertronix website and put in your vehicle information and it will tell you which one you need. Otherwise call Pertronix and they will help you. They are great people to work with. Call 800-827-3758 | 909-599-5955 for help. **Q: Will this work with a 1987 E-350 with a 460 engine?** A: It replaces points in the distributor. If your distributor has points, it will replace them. ## Customer Reviews ### ⭐⭐⭐⭐⭐ New life to old engines *by M***T on June 17, 2010* I'm not a gear head.
