This might have been asked before, but I couldnt find anything on a search so my apologies if this has been answered before. So I am looking at building my engine and the question I have does the Edelbrock Performer RPM manifold with a carb fit under the hood of a 1st gen Firebird? The guy I am talking with to build my engine is saying he doesnt think it will fit without modifying my hood. Please, can someone settle our debate about this and also maybe provied some pics of this? Also, can you list any reasons as to why this wouldnt fit, like the combination of that and a certain carb...etc? Thanks all! Happy Monday to all!
