Small block 59 Chevy ...WOW

As Don Garlits Discovered Many Years Ago.

I Think he Still Holds the Record for the Highest Speed Going Through the Traps Upside Down & Backwards. LOL

Why do you think that car weighs 5000 pounds?

A little less, especially being a race car. If I remember correctly the hardtops (Impala) are on the books at ~4200 lbs. Convertibles added about 500 lbs. Post cars (Biscayne & Bel Air) are ~200 lbs lighter than hardtops.

Are my Chevy roots showing yet? :p
 
X frame GM cars tend to launch like that. That's over the top though.

Used to watch Charlene Woods launch her stock class Poncho wagon 40 years ago. I remember standing behind this car on the line at Utica Rome and seeing the spare tire well touch the track on launch. 9" tires with a stock engine.

Those X-frames will twist pretty easily, but I think that '60 is set up to go a little extreme for some reason.

Of course I don't really know how much of the X frame is left in that '60

So tell me please, I'm not a racer, how do they bite so hard?
When a leaf spring Mopar launches, the rear raises to plant the tires. When a coil sprung GM launches, it squats, usually toward the right rear. A X frame GM (called that because the frame looks like a X) twists when it launches so it squats and twists pushing the right rear down while torque lifts the left front.
 
Yep, X-frame were under all full size GM cars '58-'64, and Cadilliac '57-66 (?). Front-to-back they are strong. Side-to-side/twisting not so much. If you jack up one corner on a hardtop or convertible car the doors will not open. Actually they twist so much that the '62-64 hardtop cars are bad about ripping the top of the quarter panel where the C pillar comes down. That's after many years and miles, but it is common. All of that was in part to have a "jet-smooth" ride.

Pontiac or Olds had a better, modified version with side rails.

Having never owned one, I've always wondered how you remove the driveshaft in one of those?

Straight out the back (axle side). It's a two piece shaft supported by a carrier bearing inside of the tunnel.
