Mains: 2.45" Rods: 2.10"
The standard crankshaft journal sizes for a Holden 304 are typically 2.5591 inches for the mains and 2.0866 inches for the rods. It's important to verify this information with a specific engine or consult the manufacturer's specifications for accuracy.
No, the crankshaft from a 366 Chevy engine will not fit a 396 Chevy engine. While both engines are part of the Chevrolet big block family, they have different specifications, including stroke length and journal sizes. The 396 typically has a longer stroke and different mounting characteristics, making them incompatible without significant modifications. Always consult specific engine documentation or a professional for precise compatibility details.

The AERA ( Automotive Engine Rebuilder's Association ) is a great source for this kind of information. Their website is at the related link below. It does require a membership.
There are several detailed publications with this info. Your public library probably has a manual for your car with this info in it
The engine sizes for the 1972 Chevy Cheyenne included the 250, the 262, the 292, the 305, the 350, and the 400. The 454 was also offered for the 1973 model year.
For a 2003 Chevy Suburban (all engine sizes), the recommended viscosity is 5W30.

What are the speaker sizes on a 2010 Chevy Tahoe
New answer- A small journal has 1/2 in. Rod nutsA large journal has 9/16 in. Rod nutsA previous comment was "On The Engine There Is A Large Journal This Is The Crankshaft Journal That Is What They Must Be Talking About. Where The Rods Go Is Call The Small Journal. This Is The Only Way It Can Be. Hope This Helps"I will presume that this question is not about the difference between 'big end' and 'little end' of the connecting rods. Use of the word 'journal' indicates to me that the question is about big-end bearing size, not 'which end of the rod is which'.Technically, of course, the "journal" is the part of the crankshaft on which the bearing in the big end rides, but the measured difference between journal and bearing-bore spec would be little more than the thickness of an effective hydrodynamic lubricating film.Presumably this question concerns the GM 350 Chevy engine; look here for more specific information:http://en.wikipedia.org/wiki/Chevrolet_Small-Block_engine(Other related wiki pages related to specific GM small-block designs exist too). There is specific information on the different journal sizes -- ISTR specific mention is made, with dimensions, of at least one version of the engine that has different crank-journal specs depending on year.To answer the specific question, the 'definitive' way would be to remove one of the rod-bearing caps and push the rod up sufficiently to get a measurement on the crank throw. Measure the crank journal diameter at several points (to eliminate some of the effect of wear), then compare this to the tech information. I believe there are ways to tell from the engine serial number, but I do not know that information personally.Hope this helps properly...Small block engines (other than 350) before 1968 were small journal (2.00 rod journal). 1968 engines (other than 350) could be either large (2.100 rod journal) or small. After 1968 all small blocks had large rod journals with the 400 having larger mains than the others.
Are the engine sizes the same?Chevy put a few different engines in the S-10.In most cases as long as the body style is not to different the swap should be ok.If the engine is a 4.3L you will have a lot of tight work as the engine is about crammed into these trucks.You will be in there a good 6-8 hours removing the engine. What you need to insure is that all your sensors can swap from engine A to engine B.Also if the engines are of diffent sizes you have more work ahead as you may have a computer swap on your hands as well. There are groups of Chevy owners that mod many a Chevy.You can get that info by searching in any search engine like yahoo or Google and finding V8 mods for them.
