Hey there,

Has anybody had any experience adding RAM Air to a 73 MachI ? I've got a Cleveland 4V in it now and am looking for a bit more HP.

If I do this, is there any guess on what increase I could get?

I have found a couple of places that offer a "look alike" kit that does not have the vacume acuated doors on it. They are open all the time. I don't know if that is a concern but the cost is about $715 compares to about $2,200 for an actual kit.

Thanks!
