The 440 for the same reason as the one I gave in your other thread. ....as I said, it isn't rocket science: the 383 and 440 are very similar only the 440 is 15% larger. Not sure what more you need to know ....and PLEASE turn off your cap locks. Dave

I'll be the "stand alone" here. Not knocking off the 440 at all, (I'm a 413 guy! ) but I'd go with the 383. It can go to 500hp, but it WOULD definitely need the better heads to start with. Other reasons for which many "may" say it's insane but: Less rotating weight (crank mass) in the motor. Strong rods (when NEW) proven to go OVER 6200-6500 rpms with a good safety margin to boot. Oversquare bore/stroke combo with a 1.89 rod ratio - great for HI-RPM HP, midrange to hi-end torque. Easy to obtain, cheap to build, but piston prices have risen lately! In otherwords, it's an overgrown 340!! Only drawbacks - it NEEDS a lightweight body to run really HARD to "coin" the sub 11 sec and faster brackets. Motor needs a "pro" type oiling system for the sub-12 sec brackets, which include enlarged main oil feed and return block passages and possibly external oil lines and filters. Helps make them live longer!! A little more work than whats needed on the 440, but they DO HAUL THE MAIL!!

Try the 383 with a 4.25 stroke and good heads, 496ci. Mine did 648 horse under 6k RPM and under 10:1. Hydraulic roller.

440 has bigger bore that helps un-shroud the valve and make more HP with the same heads. Also for the street the extra TQ is fun Any money you save buying a 383 will be lost when buying pistons. The differance in weight is minimal, not like the differance going from BB to SB and either big block build it is gonna be a pain to change plugs compared to the SB so the minimal differance in deck height don't really make it much easier. If the choice is 440 or 383 build the 440 every time. BTW after 67 the 440 and 383 used the same heads

....read the want ads and for one example...you'll see..."mopar for sale...383 with 440 heads" If the thing was that great it would run it's own heads....
You see ads like that because the seller is UNEDUCATED about mopar big blocks ... FYI the 383 - 2bbl runs the EXACT SAME heads as the 440, only difference is the valve springs .
