for the Eddie young EFI to clear the dyer kit i had to have a 5/16( i think, not sure off the top of my head) spacer made for the injection plate to sit on so the throttle linkage would clear the blower something to watch for if you have limited space

what are you going to use to run it?

We do understand this has gone from a 575 rebuild to a custom build. lol Those dyers are great blowers for the price.
