The other question you need to consider is how much HP are you expecting to make with this combo? Over 650HP stock Chrysler 440 blocks are not very durable in my experience.
I just did a 400 low deck with a 4.25 crank 6.535 rods and 4.380 bore got the kit from 440 source. Very little grinding and fitting worked slick. This was a mild 512 engine for a 4x4 truck. Small hydraulic roller 10 to 1 compression 452 heads hand ported Fi/Tech injection it made 500HP and 520 ft. lbs on pump gas and idled at 17 inches of vacuum.
