Does a '76 280 or '68 280 fit in my '78?
I'm looking for some technical help on a 280 DOHC engine. I have a '78 280SE w/ a bad engine. I have located 2 cars at the local junkyard. One is a '76 280 W123 and another is a '68 280. Both engines look complete as not much was removed on them up to this point. Will these engines be a direct fit for my '78? Obviously it tough to tell if these engines are any good since you can't put a battery in it to turn it over. What should I look for in assessing these motors? These cars have carburation, but will my existing fuel injection manifold swap?
