Going to take a crack at Index racing next year

Since I'm running EFI it would be a pain to swap to a carb for index 1 week, then back to EFI the next, then back to carb, etc. Intake is too tall for a 1" restrictor plate. The plates are allowed but no electronics. I haven't been able to find any bolt type throttle stop for the 4500 size Throttle body.

What does your linkage look like to the efi? are you using a Mopar stock style throttle cable ? does your linkage attach to the refi unit like it does a Holley carb? if it is you might be able to use a bolt system similar to my setup. Mine basically just keeps the linkage on the throttle blades from opening all the way and I move the bolt in or out for faster or slower.
