LT-1 Intakes
Ok, i have seached many different forums, and haven't found this specific info yet.
I know about the 3 different Lt-1 intakes,
92-93 (no fuel balance tube)
94-95 #10108630 (fuel balance tube)
96-97 #12552138 (fuel balance tube)
I also know that the ports were changed slightly between the last two designs. But, were the ports changed between the 93 and 94 designs? I currently have a 94 intake on 93 heads, and was wondering if i am killing some power with mis-matched ports.
Are the ports on the heads changed at all between years?
Which years flow the best over-all? I was told the 93s did b/c the fuel balance tube's indention isn't there to restrict the incoming air. True?

 

the ports are the same dont worry about it. its stock its gonna feel like its lossing power

 

The intake manifold is about the last thing to worry about as a restriction.
