Dunno if any of you have run into this before so thought I'd share.
So I decided to do a carb & manifold swap on my 383. The car has a/c and I'd like to keep it all intact. I decided to put on an Edelbrock Performer RPM I had lying around. It's a tall dual plane that I've heard good things about and I figured it'd be better down low than the Holley Street Dominator single plane that was on there before. Test data found here: http://www.hotrod.com/how-to/engine/hrdp-0712-mopar-intake-manifold-comparo/
Anyway, I got the manifold set in place, finger-started one bolt on each side to hold it, and tried to set the a/c compressor and bracket in place. That's when I ran into the snag. The a/c bracket (big heavy cast iron thing that bolts on top of both sides of the intake manifold for those of you that don't have it) won't clear the reinforcing webs at the front of the manifold. (Dammit) SO, I can cut & grind my way to success. Then I had a thought (a dangerous pastime, I know): What if I just turn the manifold around and set it down backwards? It fits but the carb pad is tilted the wrong way. Dunno if that'll cause any hood clearance issues or not but it fits. Dunno if this will make it not work as it should either....but it fits.
Now I haven't snugged everything down yet so it's not a done deal. Just thought I'd share what I discovered.
Also, anyone have any suggestions as to which way to go with this?
1) Leave Performer RPM backwards and see what happens.
2) Remove Performer RPM, modify as needed, and reinstall as it was intended to be.
3) Forget it and reinstall the Street Dominator but this time add the TD Swirl Torque spacer I have so the carb will work better and MAYBE improve bottom end output over the same manifold without the spacer.
So there you have it.
