Easy to work with....once that big plenum heats up you could idle through a McD's drive through. Can't beat them. "Old age and treachery trumps youth and enthusiasm, every time!"

I have used them on smallblocks big blocks and even Chevys.

Anonymous Unregistered A	Quote: I'm at a lot of drag strips and I don't see them on anything other than mild street/strip combos. I'm at a lot of drag strips and I hardly see any Mopars, so they must all be mild street/strip cars....... Point is; For the original poster, YES , they work great for a relatively mild street/strip car and YES, they are a lot better than the RPM carbs.......whereas a Holley is infinitely tuneable so you can tune around 90% of people's messed up combo's.......An Edelbrock, typically, needs a fairly good amount of vacuum to work good......and the Thunder Series is nice because you can slow down the secondary opening so it won't bog if you do have a motor with fairly low vacuum.......

No gurus, no secret voodoo magic, out of the box and we changed the jets a little. Just junky street carbs though. Alot of the NSS guys run them on the wedges and the hemis due to class rules and they crack off plenty of 9 second passes all the time. Todd. www.mopartsracing.com

I have one on my 427" SBF and I'm really happy with it, the only changes from OOTB is I needed to go to a dual line feed and I fattened the mid range up by using the stiffer step-up springs (which takes about 2 minutes) to bring the primary main jets in quicker (which in turn boosts the signal strength to the secondary air door). Tweaking becomes second-nature once you get used to them and I've actually tweaked AVS's to run as quick or quicker than Holleys with better off idle response and better overall drivability. For high stall converters and especially WOT it's tough to beat a well tuned holley, but to me it's really more about secondary shooter tuning than anything else, jetting and power output can be very close in the hands of a good tuner for comparably sized carbs. The eddy AVS is very responsive off idle and much more tractible (coming off sharp corners....the reason I ditched the double pumper) in a 500+ horse 2450 pound car that gets driven hard everywhere. I like them, I always had very good results with the AVS type carbs (including the TQ).
