i find it hard that this needs no jetting changes or anything wouldnt the air fuel ratio be off an dcause some cylinders to become lean ?

slick idea if it works ...run 2 different indexs

I do suspension work for a guy who uses the EZ plate. He slows his mid 6 sec. Mustang to the 7.0 index and he's deadly. I never asked him about the leaning out on some cylinders, but I will now. 

I'd think once the Carb is tuned with a plate to get the desired ET, Switching plate to move the ET up or down by .01-.02 wouln't be a tune killer as long as your not on the ragged edge as far a lean is concerned. Most cars running the Index stuff getnerally are not tune within an inch of there life anyway, most guys are conservitive and looking for a long service life not the absolute fastest it can go.

I have a few friends running the EZ plate systems and they all like it. I would worry less about causing a cylinder mixture imbalance...with EZ, than with the fixed stop on the linkage or pedal method, which also works very well in index racing. At least with the EZ deal all 4 throttle blades are WFO. On a fixed stop or pedal stop, the secondary blades are partially open which could effect the rear cylinders if the racer was on a lean tune up.

I watched a Mopar racer test his ez-plate at our last race. 500" engine in a road runner, trying to slow down from 10.20's to 10.50's to race at a Mopar event in the north eastern US. The are a nice piece, very well made.
