I’m been working on putting car back on road, received a carb kit for Christmas ,yay , this engine not original got it from a e9 guy east bay, it’s been a long time but on installing these carbs, kit built for a e-3-e9 I notice an issue- see pics- it appears manifolds are different height. I seems front is too high. Is that possible. Anyway all information is appreciated
Any info on manifolds (help)

You are aware that the engine is tilted so it is higher in the front than the rear, right? I'll have to go to my shop to see if my carbs are set up the same way. It is possible that to overcome the engine tilt the two manifolds are different heights, and perhaps you have them reversed front to rear (??)
Your manifolds are reversed, the booster port is always on the front manifold.
Hi thank you everyone for the pointers, anyone with carbs have manifold numbers, I’ve swapped them, in picture booster in wrong slot- main thought for me is as iwhen installing throttle linkage manifold not level touches fuel pump. Installing air cleaner front carb touches hood. Anyone else with webers ? I’m just mocking up and haven’t tried starting. Just seems off but maybe it’s just me….
You don’t need a number just move that rear manifold to the front. They will not be level, look inside your air cleaner, it will make up for rear carb being lower. Weber carbs touching hood and firewall is a known issue
You have the correct manifolds, there are no others

The Weber carbs don't touch the hood and firewall, but a stock air cleaner will. You can mitigate those problems by:
- Not using JAM adapters to connect the Webers to the stock air cleaner. The JAM adapters bias the air cleaner rearward. Other types of adapters are discussed in this thread: https://e9coupe.com/forum/threads/wtb-weber-adapters-for-stock-air-cleaner.34626/
- Using thin heat isolators between the carbs and manifolds to drop the carbs a bit.
Are you certain you have BOTH manifolds? Or do you have two of the same number?
If you find that you need a set I have a pair available.
He has the correct, original manifolds, the vacuum ports are the clue
