i pulled a 305 out of an 84 Camaro about a month ago- pulled the heads before that, tho, and learned that the best method is to leave the exhaust manifolds ON the engine and just unbolt the "y" pipe from underneath- or break off the bolts, as happened to me. if i was gonna just pull the engine, i would have left the heads on, but i thought i was gonna do a head rebuild or something and get it running again- you know how that is. it only took me 2 hours of swearing and screaming and kicking stuff to get the back 2 bolts out of the pass side exhaust manifold. great design there. unbolting everything else took a grand total of about 2 hours, as already stated by someone else. and i took my time, and only used the Sawzall on the exhaust hanger by the tranny mount and on the 2 bolts where the pipe bolts to the back of the cat.
you don't plan sincerity.
you have to make it up on the spot.
wanna hear about 20 years ago when i was too smart to know any better?
