Question

Thats a new one on me,I have heard of a 444 done that way.One of the first 392 hemi strokers was the Donovin 513 so I guess with enough grinding anything is possible.

you need a 4.25" crank and stock bore for 503...not 3.75" like the 440

Default It don't compute

Bore squared times the stroke times .7854 times the number of cylinders = the cubic inches.

Assuming the block is standard bore the equasion is this. 4.34 squared X 3.75 X .7854 X 8 =443.8044 cubic inches. Or what everybody calls a 444.

BTW: rods have nothing to do with the total cubic inch displacement.

Your freinds mind is getting tired. Not full of poop.
The Chevy rod deal is with a MoPar off set crank ground to I think it is 3.900 for a CID of ..errr.. I forget. 468 @ .030 overbore.
I think muscule motors has this writin up. 474 sound right to anybody. Or is that the 383 and a 440 crank?
Anyways......
The use of a 400 block and a 440 crank will give you a 451 cid engine. A very nice combo because it has a very light rotating assembly. Though not really a big stroker with just 11 inchs over a 440, but it's popular to do.
Swaping in a 4,15 crank will yeild around 500 inchs depending on overbore. You'll want some crankin heads for this otherwise you might as well just have built a 440/451.
