Will Trailing arms work with 700HP ?? Calling all DRAG GUYS!

No problem on being open-minded. I'm here to learn,and help if I can.
I drive this truck about once a week or so, and it's street manners aren't all that bad. It's not going to out-corner a 'Vette or float down the highway like a Caddy, mind you, but considering that it weighs 3800 lbs and runs what it does with a small block , I'll put up with a little less handling ability and cushy ride. Seriously, it's not as bad as I thought it would be, even with the trick springs and the 90/10s up front.
As far as hp, I've never had the motor on a dyno, so I can't quote any dyno figures. I can say that judging by what my handy-dandy Moroso slide calculator says, it made right at 780 hp with my old motor on the spray. The old motor was an iron-headed 377 that I was spraying 200 to, and the motor that's in it now is an AFR-headed 421 that is a good deal stronger than the 377 ever thought about bein'.
I'd say that the 421 is making somewhere around 600-625 on steam and around 850 or so on spray.
I've seen guys go quicker with less. It's all in the combination, and how willing you are to make slow, patient changes to try and improve what is already there.
