I have a 85 f 150 with a efi 302 i want to swap out for a 351 i read some tech on it in a I want to do this swap only and am wondering i that i have been doing some reading and it seems on the speed density 302 units you can swap cams without throwing the comp into convulsions. Is this true if so then to what do i need to do to convert a 351 to mass air if the one i find for my swap is speed density? I would get the mass air off the bat but the newer mass air engines i am going to guess will cost more then older speed density or none efi engine..on that note if i get a older short block for the stronger block will the newer efi still swap over? I will also be attempting a rebuild on the aod in it with a tci rebuild kit so any info on that would be helpful as well
