I have been lurking on this forum for quite some time. My father owns a 1966 convertible big block car that has long gone the 427. My question is about the structural rigidity of the body and frame. If someone was looking for 700 rwhp in a convertible car, what would you trust in suspension modifications? I dont really want to keep the leaf springs. The car would not be be tracked. It would be a driver and show car, but I want it strong enough to not cause flexing and fiberglass issues. Also, what company would you trust for these modifications at current technology standards. This project is on the drawing board and I would like you guys input.
The L-88s were 580hp; a fella on here runs a stock C1 suspension with 500hp as well.
So I don't know what you think you need to beef up. And the C2 ladder frame is actually pretty stout.
As noted you aren't going to 'hook up' with 700hp with the tires that will fit under an untubbed C2 anyway. Save your money for the tires you are going to wear out.
Since it was originally a BB car, I would carefully inspect the differential crossmember gussets/sombreros. They are a bit of a weak link.
These pics from JohnZ outlining the common problem....
Before body-off on a '67....The Driver Side on this one was poorly repaired years ago. It tore away from the frame and was brazed, hack welded, and covered up with heavy black paint. It was recently replaced as part of a body-off chassis restoration.
After body removed and media blasted....
Replaced......

Thanks for all of the replies guys.
Rich, I will look into that area of the frame. I know the history quite well on this car and I dont think it has any major frame issues. But the car was heavily raced on the street back in the 60s-70s. And I have heard the car pulled a boat a few times. Yes, insane I know. Let's just say that my cousin was a free soul back then. lol
1966 structural question
