I hope this thread gets a lot of responses - - - - the reason being that my Son just had a 2bbl Holley removed and replaced with a 4bbl Eldebrock on their '65 Mustang - - - the builder friend really ran Holleys down but then my Son's Nephew, who fancies himself a Car Guru, nearly choked when he learned of the swap ????????????? Is there really an Always or Never when it comes to Carbs???? no hi'jack intended, just wonde4ring?
