I have the marine intake on my challenger. I made my base plate out of a piece of 1/4" aluminum and had it powder coated black. I am runnig 2 of the 450cfm mechanical secondary hollies. I put a 50cc pump on the back carb. I used the 20 dollar Mr. Gasket progressive linkage that Jeg's sells with no problem. I have the rear carb set up as the lead carb. I had to make an adapter bracket out of 1/4" square tubing that bolts to the carb studs so the lid holes will line up. I am running a chrome six pack style lid. (for a hundred bucks, you can't beat it.) It may be a little under carbed for all out HP, but iit responds like it is fuel injected. My girlfriend loves to drive it. I really built this car to get her out of my road runner. She used to drive that all of the time. If anyone needs to see some pics, let me know. I'll try to post some.
