Your going to have to try pretty hard to only make 325 HP with any 440 motor 9.5 to 1 compression with decent stock type heads dual plane intake and 750 CFM carb. up Been there done that work shruggy
If you do decide to dyno test it let us know your results and what brand engine dyno up
All the pump gas iron head street and strip motors I've built,35+, have all made at least 400 HP on CA pump swill on a DTS engine dyno in Ontario,CA work
The last one was more of a all out street terror, it made 535 HP with a single 850 CFM Holley on a Eddy RPM dual plane intake boogie up devil
I haven't built and dyno tested a stock stroke 440 motor since 2002 or so shruggy
Stroke it with big heads and hold on to your seat belt grin
