I'm a fan of the Vegas and Monzas as a good drag platform... very lightweight and little effort for chassis modification. I guess they are getting harder to find these days though... a mid 80's camaro is good and much easier to find but more difficult to get the weight out. The mid-80's mustang especially notch back are also very popular... I think the notch is sturdier... I see many of these at the strip.

It's still heavy, but I love my Firebird...
