My husbands is a 400 4speed, but mine is a convertible so I think I win. maybe not in speed but for sure in the "Cool" department.
The other coolness that you probably haven’t thought about is in the engine itself. If you go to a cruise night or a car show and park the cars next to one another, your engine compartment will get many more looks, questions and pictures. You can almost bet it will be the only OHC there. Furthermore many of the people will never have seen nor heard about this engine. You’ll get questions like, “Is that stock,” “Where did that come from,” “Haven’t seen one of those in 20 years,” etc. Yes the 400 is definitely the quicker of the two but IMHO the OHC has the coolness/uniqueness factor.
