Found this item in Classic Motorsports mag. Throttle bodies that look like classic carbs.

 

Looks interesting

72 body and block, everything else 71, Tokico springs, Illumina, R180 CLSD, 83 close ratio, 3.90 gears, Ztherapy SUs, BRE 15X7 Libre wheels and BRE front spoiler.

 

A few z builds I follow on instagram have them.  They look pretty sweet.  I hope they do OER/ Mikuni copies as well.  

These have been mentioned in the past. I think it is a beautiful way to achieve EFI. Might go this way one day

@zKars is playing with a set of these for his 510....
