Will subframe connectors be enough?

I am putting together a 75 monza 2+2 for a street/strip toy. I am putting together a 406 with 2004r and hoping to hit around 500 horsepower. If I just put subframe connectors will it be enough to keep the body from twisting. I was looking at the subframe connectors from southsanantoniofab. What do y'all think?

If you're putting 500hp into and H-body and taking it to the track, you might want more than just frame connectors. If it goes in the 10's, the track tech inspector will most likely want to see a 6-point roll bar in there as well.

I understand the raceways rules for safety and I know how important it is, but I was wanting to know more about how strong the chassis is because I've heard they are really weak and will tweak easily. Is this correct, will 500 hp tweak it?
I appreciate your reply spencerforhire

In my opinion, the frame connectors might not be enough by themselves. I don't know if you will permanently "tweak" the unibody, but it sure will twist and flex.
This is all dependant upon being able to get the car to hook; the better the traction, the more it will punish the car.

As mentioned, traction is the whole factor. Do you plan to tub the rear and put some big meats on there? With street tires you are more likely to just spin the tires and preclude any twisting. If you really get it to hook then you better consider some additional upgrades. 500 true hp is a lot for these little unibodies, so upgrades may be suggested to keep things together.
