Throttle body spacer
Just curious if any of the forum members have had experience with the TB spacers and if it was a worthy mod? I have seen nice dyno gains with these used on 88-97 Chevy trucks, but wasn't sure if the same would be expected for the EFI460?
Thanks for your replies

The purpose of a carb spacer was to give a little more room for the air/fuel mixture to bend around the bottom edge of the carb flange, into the runners.
For EFI, since there is no fuel vapor suspended in the air at the throttle body(s), there is no point to having a spacer.
