.030 350 block makes 355 unless there is some new math out there
Just change up some internals to make it a 383 :)
actually 382.6 with a 3.75 stroke 400 crank
Sam it would be a 355 with all 350 stuff.

Small block chevy 350 4 bolt main block bored .030 over making it a 383 block. email for more pics and casting number. asking $250 or best offer. Must be picked up.
No, Sam is right. The guy is advertising a 350 block as a 383 because it's been bored 0.030 over.
Ok, the glass is half empty.
it's just a block. Could it not be either?
It has been a long time since I purchased any small block stuff but 250 seems like a decent price but, that too is just my opinion. 8)

Mark,
Ask him if the distributor is in front or in back. The only 383 'BLOCK' I know of is a bbMopar. :roll: :roll: :D :D

I have a 350 bored .040 over, and thought that was a 355.

IT'S just a block so what is the confusion? the crank that's used will determine the ci. :?:

Stock 350 has a 3.48 inch stroke.
The stock bore is 4 inches.
+0.010 352 ci
+0.020 353 ci
+0.030 355 ci
+0.040 357 ci
+0.050 359 ci
+0.060 360 ci
All are rounded figures.
I have an Excel spreadsheet with the cubic inch formula.
If you want a copy, let me know.

I can't get the alt codes to work on this keyboard to type the "pie are squared" formula so..
Pi x (Radius x radius) x stroke x number of cylinders

Its (bore x bore x stroke x 6.2832 ) sbc 350 would be 4.0 x 4.0 x 3.48 x 6.2832..
