T Trim too much power?

[redrider]

I have a 347 Coast High short block with ported edlebrock aluminum heads , a steel crank, forged pistons, a main girdle which can handle 600 hp according to the engine builder. With a Vortech T trim will I be pushing the envelope or should I go with an S trim with 10 lbs?
