    0-80804RDX is rated 2.5 out of 5 by 2.
    Rated 3 out of 5 by from Nice features good looking carb The jury is still out on the performance of this carb. Definitely not out of the box tuneup. Thete are still issues that I feel are tuning issues. 2000 rpm idle out of the box.Things such as this has made me leary of the actual upcoming Tomtrack performance.

    Rated 2 out of 5 by from Follow up on Holly Ultra XP 850 I bought this about 30 days ago, installed it, made minor tuning ajustments as required by Holley. Out of the box idle was set at 2000 rpm!! Took it to the track next day...it is a non performer with my setup. Was not specified correctly and wont work for me. My car is a full on racecar w/nitrous, not a street/strip setup. Overall it won't work for me. Looks nice but no go!! I am returning it to Jegs. I was explicit to Holley about my specs. and I got a off the shelf multiuse carb., not a true race carb. as they said.
