I used a set of 90 fox pistons and rods, balanced the rotating assy. Ported Gt40p heads,ported gt40 upper and lower intakes, and a B cam...if I remember correctly on 14 psi that motor on a master power t76 pulled 527 at the wheels, lasted almost two years of really hard abuse.. I'll have to get ahold of my buddy to make sure that was all that was done to it..The most I have ever seen a stock block do personally was my buddy robs car on a t70 at 18 psi if I recall, I know it pulled 618 rwhp and 640 or so torque.. Lasted two seasons, but on 14 psi and made 535 then.. But that a full top end and tuned by adam,one of the best at cincy speed..this is the car btw..
This year.. At the auto show
Last year at the track..
Just goes to show you stock block can do ALOT.. But it has it's limits.. Good tuner and quality products and you'll be golden!!
