Fbody cage help

On an LT1/LS1 Fbody when is a cage needed? I'm really bored and was planning out an LT1 car build I might start in the spring. Acording to Desktop Dyno I'll be putting 489/478 and I'd like to run a 100 shot. When you reach a certain time in the 1/4 and its required do you put it or do you get to the point where you need one from power first? How fast is 500/475 really going to put me with and without nitrous? Dumb question probably but I've seen people with like a CAI and exhaust on an LT1 car with a cage and I've been to Ubly and seen a car run a 10.50 at the track with no cage. Stuck one tire and the other came about 18in off the ground.

Thanks
Tom

6 point needed for 11.49 to 10.00 in a non-vert with stock floorpan and firewall.

10 point needed at 9.99 to 8.50 in a non-vert with stock floorpan and firewall.
 
How fast is 500hp/475tq with a 100shot gonna put me? How fast without the 100shot? I don't plan on putting it in this winter or anything. I'm just seeing about how much a build would run. 6pt, steel, low door bar cage........$850 installed?

your price on a six point mild steel is right on track, thats what i charge to do them, i would suggest an 8pt, it will tie into your sub frame connectors. my .02.

I planned on having sfc's but how do you tie it in? Just wondering, because there is no way in hell I'm planning on doing my own cage

It's a 408 STS car. This isnt' something I build overnight. It would take me a few years. I'm just trying to think of what I have to expect over the longrun
