Hello, I can currently get ahold of either a 4.6 ltr. DOHC out of a lincoln mark viii which is from what i hear pract. the same as the ford cobra 4.6 dohc minus different intake, crank but ill be building it anyways so that doesnt really matter, or a 351 EFI motor. My delima is i have no clue which would work better and be easier for the swap? ANY and ALL information will help. What all will i need in order to do the swap and what will i need to change. (Clearance is not an issue due to a 3 1/2 cowl hood
)
