I know that Ted has done some great testing on manifolds for the Y Blocks & am wondering
if he has done any testing for the different dual 4 bbl manifolds (both stock & aftermarket)?
Thanks
Jim

Jim.  Ted has posted a number of terrific technical articles on his Eaton Balancing web site.  Click the links below for the listing of all y-block articles that he has provided, the article you've asked for pertaining to dual quad intake manifolds used with FoMoCo iron cylinder heads, and an article pertaining to the testing of dual quad intake manifolds with John Mummert's aluminum cylinder heads.
