ok i have a 383 sittin in the shed...its one ugly motor (some genius put the distributor in the front of the motor and cocked it side ways, now its a half cocked ford big block i guess. ok the jokes are over now

i hear about people putting 440 heads on these and doing some other things to them to gain a little power. i know nothing about dodge or chrysler at all. does the block have clearance to put a crank from a 400 in it or are the blocks the same bore and stroke? what about the 440 crank and rods?

i have a friend who races an 8 second road runner (gang green in northwest indiana) and has a few 440s laying around for just the blocks. needless to say his shed has old 440 heads intakes and bottom end pieces everywhere i can probably trade a case of beer for.

You can use a 440 crank but you'll have to have the mains turned down to match the 383. There is room in the block for that kind of stroke. Add a set of KB (451) stroker pistons (they have several types and you can use either the 383 or 440 rods depending on which pistons you decide to use). Then add a set of 906 or 452 casting heads and you're in business. You can also go to 440 Source.com and take a look at their stroker kits for the 383. With one of those you can take your 383 up to 496 ci. Keep in mind that you can't swap intakes between the "B" and "RB" blocks so when it comes to an intake look for one for a 383 or 400.
