My new 340 at the track

finally someone said it. i AGREE 100%. it's all in the combo on how well the parts work together. i still run a SFT and ductile iron rockers.
the 360'' i had in the car ran 10.20 @ 130. in the car now is a 340'' and it's been 9.70 @ 137 with the same heads and cam that were on the 360''
Not arguing but i am honestly curious, wouldn't running a 408 or whatever stroker size make it easier on parts and less chance of having issues from stressing things soo hard to make the same power?
