For your consideration is a Holley carb conversion package with everything you need to run. Includes 240Z SU type intake manifold, 4 barrel conversion manifold, 1 Holley 390 cfrm in good condition with fresh rebuild, 1 spare Holley 390 carb of unknown condition (may need rebuild), linkage arm, and chrome air cleaner with filter. The 4 barrel conversion manifold is an odd beast for sure. Looks like it was made for a blow through turbo. It really drops the carb down low and has connections on the bottom for some kind of cooling (or heating?) system. Really interesting piece. I took this off a ITS race car we are currently restoring. Going back to SU's. I tried to take lots of pictures. Asking $500 for entire setup and free shipping in continental US.
