Carbureted LSX forum - Anyone install their Performer RPM manifold "backwards"?

I've currently got it installed in the standard orientation with the MSD box mounts to the front.
Considering flipping it around for a couple of reasons:
1. It'll look cleaner w/o the MSD box mounts in the front unused.
2. I can use the MSD box mounts for wire supports and a MAP sensor bracket instead.
Anyone do this? Performance wise it doesn't matter correct?

Its milled with the carb leaning forward so it stays roughly level when installed in the vehicle. This would be way off if installed backwards.

Interesting... I had no idea. Thanks.
EDIT - Yep... looked at it in the garage tonight and it's definitely angled.

To be honest I feel the box gets too hot mounted on the intake.. Many have said its not heat sensitive but I still dont trust anything electronic near that much heat

I'm not mounting it on the intake... never planed on it.

just get a angled carb spacer and that will angle the carb back the other way...
or have it milled so its angled the other way

I know my Holley 750 dual inlet won't allow me to mount msd on the intake, I'm going to run a 1 inch spacer so I can mount it there. There's no coolant in the manifold so the rubber mounts should isolate most of the direct heat transfer to the msd box...just my 2
