Pic of the Edelbrock 2X4 set intake I hope to use. It looks like they may have the top on backwards. Im thinking the lowest should be on the front and the highest one should go on the back. the number on this intake is a TR5. Guess I'll do some checkin on this intake. I bought this including both carbs and linkage for very little so if I have to change direction its not that big of a lose. I want this set up to work because it would be a wow factor! I'm sure its going to need a hood scoop once this is on. lol
