RR ..... so you are talking about the SM for the A engine? I think I have one of those but all I have ever used are the ones for the B and RB.

There are some "dams" in those SM intakes that you have to wonder why they are there. ESPECIALLY the dams in A engine one. There has to be a reason for that because it would have been EZier for Eddy to build them without them.

I will see if I have a pic.
