Is it possible to get 750 horsepower out of a Plymouth 440 cubic inch motor?

What bore would I need?
Would I need to swap cranks out?

Oh yeah it's definately possible... costs alot though... I got a buddy that has a chevy 502 big block in a 1972 nova that has been bored, stroked, blueprinted, a high lift cam, supercharger, and 2 four barrel carbs that is pushing pretty close to 1,200 horsepower... he's got about $20,000 in the engine alone..and is still street legal... totally brutal car, wheelie bars and everything.. kinda makes your heart stop for a second even when he only guns the engine at idle.

i run a 455 bored and stroked with lots oif go fast goodies internally. It cranks out 835 hp at the rear wheels. 750 is entirly possible from a 440

yes ,but as close you can add 150hpb you already have more than enough with those monsters 440 magnum 375phb to 450phb.nitrous,supercharger headers .

Yes. $$$$$ Your looking at about $10,000+ to do it right.
You don't need a supercharger or nitrous, you can do it on strait motor, but you would have to run high octain racing gas.

If it was bored. and supercharged with a fuel injection system. better make sure its built solid for the pressure needed.
