8 1/4?

i already got a warmed over 340 in the car just gotta get the 7.25 out of the car before it breaks im tired of taking it easy.do you think the 904 would be strong enough or should it be a 727. i have a 727 i just need to rebuild it along with the rear.

The 904 should be just fine with what your running,i've got 3 seasons of racing on mine behind a 416 stroker still going strong..
