Right. IMO, that’s asking a lot even with a “big” small block. W8-W9s that flow 350 cfm of air plus a real intake, 2”+ custom headers, Jesel belt drive, T&D Rockers...Start saving up now.
Is a power adder in the equation or does it have to be N/A? That would be easiest. Tube frame truck should probably accommodate whatever plumbing is needed. Turbo, Nitrous, Procharger... all would work. Do you have EFI?
Obviously 700hp N/A can be done but it seems like you’d be starting behind the 8 ball. I’m a small block guy myself but I fon’t play in the W head sandbox. I also understand that BB torque is different than a small block in that it’s inherent in the architecture of the motor. Why not take advantage of that? These days 700 hp and 650 ft lbs of torque under 7K RPM N/A is ‘cake‘ with a big block.
My basic iron head 340/416” made 500 ft lbs. of torque but only 500 hp @ 6,200 RPM. I don’t think you can have real big torque numbers without sacrificing some top-end power and vice-versa - if you’re spinning the thing to the moon to make power in general you’re going to be down on torque.
What do I know though. I’m sure I’ll get slammed for all this. Prove me wrong!
