The 1980 (first year) motor's shouldn't have an ECM (excpet in California). Export 1981-84 may not have one either.<P><BR>But to make life easier, to convert a ECM engine to a non-ECM, you will only need a different carb and distributor. There are many carb choices. A vacuum advance distibutor from a 1978-80 231 V6 will work with the 252. <P>The 1979/80 exhaust manifolds are much bigger than 1981/84. (They're also the same for 231's and 252's.)
