ok im gonna try a 351w swap, i have two long block 351s , ones out of a 86 vrown vic and the other a 91 crown vic. both are in fine working order they just havent been used in a few years. does anyone know what heads are on them? also both were carbed, and is it a big deal with the switch to efi, i have a 89 with bad motor and was hoping to do a swap with the short block. what im hoping is i can just get an intake and call it a night. possible, thx for input.
