Re: Holley Truck avenger
I had some stall, flooding issues off-road. It only happened on VERY steep uphill, downhill situations. I
installed an Edelbrock off-road needle and seat kit and haven`t had a problem since. I can`t say what I get
for mileage now because I haven`t checked in a long time. A couple years ago I was getting a little over 14
mpg if I was light on the skinny pedal. Thats with a performer intake, MSD Pro Billet dist. and MSD 6AL box.
Also stock exhaust manifolds that dump into dual 2 1/2" pipes and Dynomax turbo`s. I`ll also second what
alesko mentioned in his post in that the carb has been trouble free the 5+ yrs. I`ve owned it, and it was on
the Jeep when I bought it. I`m not saying that Holley`s are bad, I had a 500 cfm 2 bbl. on a 304 in my last
Jeep (`73 CJ5), and it was an exellent off road carb. It never once flooded on hills, I liked it alot and never
had a problem with it. I never had any good luck with a single holley 4 bbl. I owned, ALWAY`S blowing power
valves. I alway`s liked the Carter AFB`s, which is what the Edelbrock carb`s really are.
