I don't know if this has been asked yet but how fast do you go with trick flow 240's ?

I think Greg’s assessment is about right.

Street/strip, and bracket race up to about 600-650hp, especially with motors in the 470ci and smaller range...... the 240’s make sense.

Get into that 500” and up range, and 650+ hp(or stock stroke combos looking for pretty high rpm peaks)...... the 270’s get the nod.
