iowapub, what emissions regulations do you have to conted with on a '78 vehicle? I'm fortunate in that in my state, any vehicle older than 25 yrs is exempt - and my state is pretty strict. I think you could meet your goals with a mild 400. I know if it were me, I'd be kicking myself for not going with the bigger engine later on...but that's just me. </div></BLOCKQUOTE>
i agree on the cid comment.
i'd bet on a 78 the main concern will be a visual inspection. the 75 400 should have enough emissions to pass this. egr,vapor canister ect. the vapor system should adapt over from the 301 in the car.
a high flow convertor should clean the exhaust up also.
a mild cam in this combo will really wake this car up.
throw a 3:23 diff in it from a monte ss and you won't know it's the same car.
