Heres a combo that my friend Robert just finished and its going to be in CarCraft pretty soon. Stock 440 block and crank with offset ground rod journals(470") and basically a 7.1" long BBC big and small end rod, 10.9:1 compression, pump gas, Box Stock Victor heads and manifold with a .670 lift solid roller with 270@.050. It made 711 horsepower with a 1000 cfm 4150 carb. The heads are like the 2nd set and T@D made the rockers for them using these heads. Seems like 700 horsepower just got a little easier to make. There was very little tuning on the Dyno and more is to come because the engine is still on the Dyno.
