My opinion... Impco 425 is the best fuel metering device you can use offroad. But unless you are offraod only, I don't recommend propane. My Holley Avenger didn't impress me at all. I was constantly tuning it, depending on the tempature. I could literally tune it in the AM and by the time mid afternoon hit and it was hot, I would have to adjust it again. Granted that may have been 'my' Holley. I could of had a bad one.
