Front end Frame twist
The front end /frame does seem to twist from the torque produced you'd think the car was a unibody. One of my favorite cars the Old Chevy2's I'd love to transplant an LC2 into a 67. If I did happen to transplant an LC2 into a Chevy2 I'd definately upgrade to a stiffer subframe.You think the Buick frame twists, well that sub frame is way worse! Anyway back to the subject at hand stiffening the frame. They have come up with bolt in subframes for these cars as the stock sub frames easily twisted and moved. Some of these subframes actually have bolt on side struts/bracing that bolt to frame and to firewall giving the car a more rigid subframe with "less twist".I'm sure it's these struts that stiffen the subframe up. You could have have your Fabricator do this, bolt-on frame to firewall struts, that way when you needed to work on, pull out engine or what ever , you could remove them temporarily. You can only put on so many braces on from the same plane. Need to brace/triangulate from another angle. Frame Chassis building is a science art and It's amazing to see the work done on some these cars , just amazing. Built a mtn bike frame once and that's the limit to my knowledge of working with chrome moly, it's still working 20 years later, so even a blind squirell finds a nut everynow and then.
Another thing I've noticed that might help on our cars(maybe overkill), On all those unibody cars Camaros, Novas, Mustangs to stiffin things up even more. As you knowTriangulation is every thing, of coarse they have to also utilize subframe conectors etc,etc. noticed on the chassis/subframe for an Eleanor Mustang type build where they used triangulation in the engine bay they actually tied into the shock towers to firewall with struts that also came forward to tie into a fender brace/strut. They also used a solid aluminum engine and mid mount, don't think you need to go to that extreme. All this triangulated stiffening up would be custom-made one off for your car, you might beable to modify Camaro shock towers bracing/struts, even some them braces off some them Ricers might be a start I'm sure you fabricator could do all this, a roll cage for the engine bay
. Sounds like you've already put on all the bolt on frame braces and bushings available for our Buicks. I'll shut up good luck with working things out.
