I would recommend the 57 and up 4v intake and 57 and later dist. Keep the 4v carb in the 400 too 500 cfm range, timing it approximately 12 degree at idle being all in around 36 degrees (3000 rpms). I had a 57 ford custom 300 4dr with a 272 2v holly that would clean the clock of my 57 ford convertible that had a later 302 V8, my friends 61 tbird 390 375 hp, and would eat 327 chevys and spit um out on take off or long run. As to this day I don't know why it ran so strong but it did and that was back in 1966 and 67. That's THE ONE I've always regretted selling.
