: Can anyone tell me what if there is any reason that a Holley 4150 can't be installed rotated 180 degrees?
: Any advantages?
: The previous owner has set my car up this way, so the linkages and fuel line plumbing is reversed from a "normal" installation.
: The application is a V-8 powered Mod class autocross car with a single plane manifold.

: Daryl,

: This is a good question.
: I put my 215 in a mid-engined car so to make the linkage correct I also had to reverse the carb 180 degrees.
: Seems to run fine.
: However, I remember about thirty years ago reading an article about carb placement.
: The authors took a 2-barrel carb, centered it on a manifold and ran the quarter mile.
: They then took the same carb, offset it forward (similar to a 4-barrel placement) and raced it again.
: Turns out when it was shifted forward it got better performance.
: The theory was that acceleration forced the gas mixture toward the back of the engine thereby starving the front cylinders.
: So shifting the carb slightly forward overcame this.
: With that in mind, a 4-barrel carb reversed 180 degrees should not perform as well as one mounted correctly.
