Aluminum 455 frame mount strength?

Has anyone broke the aluminum 455 frame mounts? Thinking of using them in an 800+HP application,with solid steel engine mounts and a mid-plate.

 

Are you asking about the mounts for the 1st gen a-bodies? That TAP sells.

 

Yes. For my 70 GS.

 

You arent going to break them.

 

If your using front and mid plates, they won't see much stress at all.......they are basiclly only there to line up. Heck in honesty if your using both front plates and mid plates you wouldn't really need the frame pads at all

 

I've them for more then 20 years on my race car,it's a 3000 pds race car that has run a best of 9.03 and 148 mph in Bowling Green,with a 494 stroker..Still there now. Bruno.

 

I’ve never heard of them failing,but I figured I’d ask. I always had the steel ones,but I’m assembling another chassis and need to install a pair. Went 9:40’s at 3900lbs before. 505”. Will be 517” now. If I ran a front and mid plate,they would just be there as a limiter,but I only plan of running a mid-plate for now. Same solid steel engine mounts as before.
