In reading all of this information, I have a few questions!
Between the 904 & 727, there comes a point where parts, for ether, become limited. Between the two;
Which one would be the better choice for a 9 second ET car.
(In my case, it would currently be a small block Duster being built.)
Ultimately, which one can hold more power?
Where are their respective Tq. & HP limits?
