340 x-block vs. 410 stroker ?

I built my car to run 11.80-11.90 and that's all it better do. I damn sure don't want it going 11.49 or quicker. I really don't want it much faster than 11.90. I don't want the car tore up.
IF 11.55 tears the car up, then most likely a 11.8 will too. Also, what's wrong with going faster than 11.50? It's not like you'll install the safety equipment, 'cause you'll not make another pass in 12 years :D
Some how I think you'd take a 10.90 if it would do it. I sure would .... :)
