Chassis reinforcement - cages, frame connectors, etc.

[BuddyP]

Hey Guys, just trying to plan out the first portions of the project and would like so hear some opinions in the direction that I should go. Project is a '68 Camaro. Want to at least start out motor wise in the 400-450 range but want to build a chassis capable of holding 600-650hp (low boost Banks setup??). May do a LS1 swap with a future blower also (450-500hp??)...

But anyway, chassis is fully disassembled. I didn't want to get into too much cutting up of the chassis. Would like to keep it fairly close to original and also just don't have the fabrication facility or tools easily at hand. I currently have a set of CE bolt in frame connectors that I will probably weld in the rear but will still bolt to the front subframe in case I ever wanted to separate the subframe from the chassis in the future. Also have a set of Poly body mounts bushings. I have considered running cage tubes from the front of the subframe (welded on) to the firewall (bolted on). Would that alone with the frame connectors make a resonably solid car? Car would not be launched hard to speak of, and won't have the tires to do so (not tubbing, will have around 9.5" wheel and 275 tire). Also it'll be strictly street driven. Again, figure it seeing no more than an honest 500-550hp at most probably.

Just looking to go in the right direction.
Thanks!
