400 sbc in a ‘70 K10

Maybe not the perfect forum for this but whatever. Been shopping for 400’s to put in my ‘70 burb. Truck is stock but needs more torque. It eventually occurred to me that GM probably never put a manual trans behind these. I see aftermarket external balance flywheels available. No problem with my SM465 and stock bell housing? Any other issues?
