Yet another 2nd Gen Camaro - Project/update

[preston]

You are wondering if the 2nd set of triangulated bars going to the firewall center area are necessary ? In either case you would still cross brace the shock mounts and bring in the "down bars" from the cage to the top of the shock towers ? I assume if you did bring the triangulated bars to the center area of the firewall that they are penetrating the firewall and joining to a dash bar ?

Just arm chairing it I would say those could be overkill at least if you are thinking more 1.75" DOM, it depends a little on how much top view angle you are getting from the cage to the shock towers. I guess I would be inclined to bring in the outside cage bars and cross engine brace, and then maybe go with something a little lighter and removeable if you still wanted to brace to the center of the firewall. You could build cage reinforcement on the cockpit side of the firewall, and provide a bolt in interface, and then use lighter weight removeable tubing that bolts on to the shock towers and the firewall reinforcement plate that I just mentioned.

I guess that means you need to find another car to buy and drive back to Cali soon or you can finish BMF and drive it back..

Not wondering so much about the second set of triangulated bars. More concerned if its better to have a full 1 piece bar coming off the main structure of the cage and coming to the front of the frame or if I can weld a short section from the front hoop of the cage.

I'm wondering if the bay bars will be weaker if they are 1 pieces of tubing welded together. And if they are weaker is it enough to cause a safety or rigidity concern. I hope I never wreck the car but if I do it would be nice to be protected

Yes, this would be the case.

I agree 1.75" is probably overkill. I was stating that the hoops are currently 1.75 and should note that the main cage would be too. I'm thinking the outer down bars from the main cage to the shock hoops will be 1.75 for sure but agree with something lighter and removable over the engine to tie the 2 hoops together. I would probably use something like 1.5" or maybe a little less for the inner triangle to the firewall. The bolt on firewall plate integrated across the hoop supports does sound like a good idea as well

Few more updates. Made some good progress on the trans/TA mounts and made some new engine mounts. took a while but I got it all in position. Engine is at 2 degrees and offset 3/4" to the passenger side. The trans mount has a removable center section and just enough room for the exhaust to tuck in. Everything should be tucked in under the frame, which will be really nice.

I still need to well in a sleeve to the engine mounts so they don't collapse then torqued down. Also need to drill the final mounting holes for the trans mount and weld the entire mount in but overall its mostly complete.






The bearing race and tape roll are to simulate the exhaust. the angle iron is tacked to the bottom of the frame

Thanks, I always appreciate the words of encouragement.




I also just about finished the front accy drive. I still need to make 2 spacers and get a few new bolts but overall its done. Hopefully it works ok.

Looking good Steve.

Quick question. Whose harmonic balancer are you using? Looks like a Powerbond unit?
