Ok Ive had my 340 idea all shot tp hell. It looks like the 350 buick is whats going to happen. I know of a few combos that would get 350hp and 400 ftlbs all at the flywheel. My guestion isnt that. Its who has the headers for this swap into my 67 special??? Or whos set has to be modified the least?? Any ideas would be great? thanks Doug
