I have a 84 eldorado that i recently let overheat an messed up the heads.im converting to a307 oldsmobile motor and wanna know more about this converse.will i have problems wit the computer system afterwards,etc.can xomeone who knw please let me knw whats the effects of swaping theses motors???...thanks..

 

Cruise, a/c, and fuel data panel won't work. Engine harness will need altered, I would suggest to find Toronado or Rivera with 307 as a donor car to have what you need available.
