I believe that the 400 is more desireable for the person who wants to drive the car.But I agree that including the original engine is a definite plus and an incentive to the originality buffs.
I own an 81 that was originally a 301 non-turbo car. That engine was the most pathetic excuse for a v-8 that I had ever driven and I happily sent it to the scrap yard. Look at all of the hemi-clone cudas etc.. I dont believe that they would be more valuable with their original 318's and they certainly arent as much fun.I don't know about you guys but when people come up to talk to me about my car they want to know if it's fast, The cars look performace oriented and with the 301 I would not have been able to out-run a mini van.
Now my car is not "fast" but it is much more fun and I would not need a quart of oil to do a burn-out if I so desire. This may all sound juvenile to some of you but we did not fall in love with these cars because they look like they get good gas mileage. Sorry for getting off topic.....What was the question again?
