I have been deep in restoring a unibody mopar, thinking about strength and rigidity (how the K frame is part of the overall equation) and the thought came to me, why did GM do a post car body on a full frame? I don't understand why it is so relevant that the shell be made stronger on a full frame vehicle. Does a GM full frame really twist that much with it's cross bracing?
There are unibody cars that can lift a hemi off the ground pulling a wheel stand, so what am I missing on the 'post' angle? I can see how a post on a roadrunner makes sense (still an unibody, they made a few that way), but on a full frame car, I am not getting it that it makes that much of a difference. Now if the car flipped over, I would rather be in a post car, no doubt on that [img]<<GRAEMLIN_URL>>/smile.gif[/img] Had to ask. I think there are some 'post' guys floating around here.... |

I don't think extra rigidity was the point. The hardtop was supposed to be more upscale in appearance, while the post was for street racers and the phone company. Rigidity was a by-product, not a sales feature.

Bob,
It was just merely a GM body style that was lucky enough to have a full frame under it...nothing more - nothing less. But when the two were combined. Yes, most definitely makes a stiffer, more rigid car. Yes....GM cars do twist....you get enough power, torque and traction and watch them twist at any drag way across the country. Dan

Thanks! I have to wonder why Yenko did not chose the post chevelle cars, as they seem to have a weight advantage for that body size.

I have a friend who owned a 1968 SS Chevelle that had a 427 in it. He blew the back window out at the drag strip. He ended up junking that car. :-(
