Use 351C/429 solid lifter which requires a pushrod .100 shorter then "FE" pushrod as "385" series lifter is .100 taller then "FE" dumbbell lifter. Am doing this conversion now using 1.80 "Cleveland" roller rockers, "385" solid lifters, BB Chev. pushrods, studs & modified guide plates utilizing John Haskell's mounting plate & stud girdle. He recommends a .060 restricter in each bank. |
