1970 Torino and Thunderbird share parts?

What did the Torinos share with the 1970 Thunderbirds? Engine? Chassis platform?

I just found a 1970 Thunderbird 2 door Landau with stock 429. To me it looks like it's in good condition for about 3k. I want to rod it out like a Torino. Just looking for a project for the drag strip. If the Thunderbird is comparable in weight to the Torino I'm pretty much sold on it. Any suggestions?

Thanks.

Engine, trans, & third member, that's about it. T-Bird is about #1200 heavier & you'll never find headers for it. Super fun car to drive & if it's the original engine the block is worth around $200-300.

Thanks for the info. Wow that's a lot of extra weight, I might as well look for a Torino! No wonder no one works on them other than the T'bird purists. I just wanted something different. This car I found is in pretty good shape, I kind of want to fix it. So it's impractical to rod it out?
