Which A-bodies do big blocks fit best in?

NONE. They're all a *****.
Take ya at least a day to remove the engine, but a small block comes right out. Headers are a nitemare, no matter what brand. You will be heating and pinging them to fit for days.

Take it from a guy who has raced a 440 Dart for years...Getcha a hot small block.
You'll be one very happy Camper.

that's the truth, big blocks have been a pain to put in, been there and done that with some friends cars. I just sold all by small block stuff, so I'm not sure if I did want to do an of those an more. Being old and chonkers and trying to reach the distributor in the back with a bad back, bad leg, bad shoulder, bad breath, not sure it would be good for me anyway. Though this 73' he has does make me want to build a track car.
