ok just today, my engine, with only 96504 miles on it developed a horribly loud rod knock, it has plenty of oil, never burnt any, but im not gonna try and fix it, im not dealing with it anymore, what i want to know that if i were to get a 305, or even a 350, would it just "drop in", i know that the tranny will fit but are the motor mounts the same, or do i have to fabricate my own? any help will be appreciated
