When you bore a 350 .030" over it's now a 355ci. The 400 small-block uses a 3.75-inch stroke compared with the 350's 3.48-inch stroke. The difference of the two cranks strokes allow roughly 27.6 ci more. Add that extra 27.6ci to the 355ci and you got a total of 382.6ci, which car crafters have conveniently rounded off to 383.

I believe that in order for a 400 crank to fit a 350 block.. the block has to be cleared.. That might be where your inches are coming up missing.. I dont know if I make any sense.. hahaha.. Just trying to help..

What kind of headers are on this?

I always calculated bore X stroke X number of cylinders X 3.14. That always worked when you calculated the bore and stroke of a 350 but I was just getting 379.26 when I tried to do it with the 383. My old automotive tech teacher showed us this way but I guess its missing something if you try to calculate anything over 350ci. Thank you for finally clearing this up for me, it was really starting to fuck with my head!

calculate your engine size by taking the square of the bore divided by 4, multiplied by pi, multiplied by the stroke, multiplied by the number of cylinders:((Bore X Bore) / 4) X pi X Stroke X CylindersFor example, a Chrysler 426 (Hemi or Wedge) has a standard bore of 4.25" and a standard stoke of 3.75". Plugging that into the above formula gives us:((4.25 X 4.25) / 4) X 3.141592654 X 3.75 X 8 = 425.59, or 426 cubic inches. Hope this helps...

i know you posted this a long fucking time ago and you might have already done it, but i built a 355 with a 490 lift comp cam, vortec heads, air gap intake, 10:1:1 compresion, MSD and had a edelbrock 600cfm. it was way to small, it would stall out at about 5000. i went with a 750 holley and would go till it came apart if you wished. it was in a 84 swb pickup w/ 3.08 gears and a th350 and ran low 14s at close to 100mph in a square heavy ass old pickup.

darcnitch is a dumbass "what kind of tranny bolts up to a 383 big block". its a small block you jackass unless youre talking about chrysler if so a chrysler transmission like a 727 torqe flite, if you thought it was a BBC then they have the same bellhousings has a small block unlike ford that had to use different ones. |
