Just a side note... although I have had trouble with my truck avenger, some of my friends tell me that the hollies in general can be a lot more finicky. If you want something easy to setup and tune I would go edelbrock route. Holleys see,m to constantly need tuning and tweaking and retuning and things that shouldnt change all the sudden are way off ?!? And to top it off I was adjusting the float levels and the nut got out of whack when I was adjusting it and now it just dumps gas right out the vent holes and I cant get it back to normal. Great, have to send it back to holley just to get the dam float levels reset lol.
