What classic muscle cars have the most hp after tuning?

[kingstang5oh]

I would like to get some input from you guys about what old muscle cars have the highest hp after being fully tuned. I would be using it for drag racing.

I have every old muscle car but they are all stock.

So whats your highest horsepower pre 80's car or which one is fastest in a 1/4 mile race?

Buick '62 Special I think is what you want for drag racing, 700HP customized car for drag.
