Great EFI

Summit RacingSummit Racing Verified Purchase

I can't say enough about this fuel injection system. I installed it on my 72 International Harvester with the IH 304 motor. It took about a day or two. I spent a lot of time trying to make sure the install looks good, like it was stock. It would probably be difficult to make this look good on a "Show Truck", which my Scout definitely isn't. Now my truck starts up, first turn, every time. Even if it has sat for a month. Truck runs great. My butt dyno says I might be somewhere near the stock 130 HP! If I ever use a program it yourself EFI again, I will install an O2 gauge or get something I can monitor the exhaust with to program it a little better. I feel so firmly about Holley Fuel Injection, I will be installing one on my 68 Lincoln Continental. If it runs anywhere near as well as my Scout, it will be money well spent! ...read more

I am pleased with the fuel injection system. Seems pretty easy to adjust. Called technical support twice, they were helpful and answerd my questions. Wasn't sure it would work out well for my '72 Dodge Power Wagon, but it has! Would recomend this product! Only a few miles put on system, but so far so good!
