It doesn't fit.  I'll post photos later.

If the manifold isnt homemade then it will fit under the hood with an 8x2 air cleaner. Ive run both SU's and 4bbls on my car and their performance is very close if not identical. 4bbl setups are worth more than SU setups if it has an 8007 390cfm on it or 465cfm

i"ll have to check which carb is on there. Actually runs pretty good with it on there.

if you are going to sell the 4 barrel intake. I know some one in our club that is looking for one. years back a friend had the set up it run fine but he had to clean the plugs often. its hard to tune it so you go rich to balance the lean ones and thats how the problem begins.
