Which A-bodies do big blocks fit best in?

'67-up has a larger engine compartment than the early A's. The lowdeck is easier to install but still a royal PITA, true.

But it's worth it when you hit the pedal. I wouldn't trade my 451 for anything unless it was for a 470 or a 499

Id go with a duster,demon or dart sport

The engine bay will be just as tight byt at least you'll have room for tires in the back
Good point. You can fit a serious tire in the back of a Duster/Dart Sport without even moving the springs in.
Even better if you move them in. :)
