At the risk of Cool Whipps telling me to keep my opinion to myself, make no mistake the crossram is a race intake. Basically it is a tunnel ram with the runners laid down horizontally instead of vertical on the tunnel ram. With the crossram run the correct part number Holley carbs that work in unison with the crossram it looks like you have those carbs from the pics but I would recommend verifying they are the correct carbs.I could give you sources for parts, linkage, the correct jetting baseline as per Mopar tech bulletins from 1968 etc as well as a good source for the seat covers and brackets, of course what do I know I am just running that exact set up in my 68 Dart. PM if you need any info so Cool Whipps won’t get upset.
