can be both ,i have a 350 010 2bolt main
Yes the crankshaft for say a 350 4 bolt and a 350 2 bolt is the same the only dif is in the block itself. Just make sure to check bearings to make sure the cranks are the same for bearings and have not been turned that would be the only dif in crank shafts the size should be on the bearings std., .001, .010 .020 and so on
The Cylinders Have Been Bored Ten Thousandths Larger Than When It Came From The Factory. My answer: I don't think the question is about oversizes, few 350 engines are bored .010" over. I believe the questioner was wanting to know about the famous 010 blocks which used to be searched out by the racers. The 010 comes from the casting number of the block. As in 3970010, or something similar. These desirable blocks were reputed to have a bit of added tin to the cast iron mix for a harder stronger block. Many came with 4 bolt main bearing caps. 010 and 020 cast on the front of the blocks is rumored to be alloying metals added during manufacture by GM.
Well, it been a while, and I am working from memory, but, the 010 at the end tells me heavy duty, maybe truck. Most likely 70's, and a 4 bolt main engine. It may even have had a 186, or 041, or, 441, casting cylinder head on it. All 3 are desireable units today.
The 010 block was the most common 350 block. It can also be used to make a 302 or 327.
Go to search on your computer and type in small block Chevy engine ID and you should find your answer there.Most 350s id#end with 010,which is a early engine,and if heads are off there will be a small hole between the two center head bolt holes.But the best way is ID#s.Hope that helps.
Blocks with the 010 casting number have a higher nickel content and are more desirable for performance applications.
Thirty-four million, seven hundred eight thousand and ten.
10, 010, 468.
.010 is thicker than .005
.010
Blocks that have more nickel have 010 or 020 under the timing cover, meaning 10% and 20% nickel.
Since 010 = 10, 010 of 1% = 10 of 1% = 10% or 0.1
