Who makes a quality converter in your opinion? It's been 30 years since I drag raced and some of the players have changed or retired if you know what I mean.............
I used almost exclusively ATI products back then and had great results. Didn't hurt that i lived just a few miles from there shop...lol. Tried a few GER's and B & M, but wasn't thrilled with those.
Many good builders these days and i think the current users can give you some direction. Maybe start a thread to ask what the guys are going for these days? I'm sure you'll get a bunch of different opinions.:)
