here's what i'm planning on using. i bought this air cleaner at summit racing (pt# sum-g288. i think that's the #. i bought it off of the return table at summit and there wasn't any info with it.). the spacing on the base isn't right when you get it but i was able to open it up to fit the mp crossram with the correct holley carbs. if you can do any fab work at all you can do this also. i haven't ran the car down the road yet so i can't say how well it works at this time. dave
