rpm performer ?

[gtxrt]

pretty sure it a rpm edelbrock 440, numbers on bottom 19409 and 4983. will cutting center down hurt bottom end ?

Kind of looks like someone already turned it into a single plane.

I believe some did cut down the center section to solve/avoid problems with EFI systems.
Hard to tell what the effect will be, perhaps loose some torque in bottom end indeed.
