I put a Cleveland in mine, without shaving the towers. Plug access was non-existant. Tubular Automotive makes swap headers for both C and W engines. The towers do not have to be shaved, but if you like your sanity, you will shave them. Makes life a whole lot easier. The W swap headers have tiny pipes though, from Tubular... Hooker, Heddman, JBA all make 65-66 Windsor swap headers that fit our cars in various forms of bolt in... JBA mid-lengths look like they would go worry free. They are block hugging and have 1 5/8" pipes. They are also very expensive. Hedman LTs are said to fit well, but they also have 1 1/2" tubes like the Tubular parts. The Hookers have the big tubes, 1 3/4", but they require modification to fit our cars. Good luck Dave
Now we are talking! Thanks for all the replies! MaverickGrabber, I saw your web page, and I was trying to get in contact with you! What is your combo? What size pipes do you have? Another question: What is everyone useing for a lower crossmember?
