Block is just fine for a rebuild, the 10 - 20 blocks are fairly strong blocks. 4 bolt main caps aren`t important unless you plan on making over 500 horsepower. 4 bolt main blocks were mostly used in heavy duty applications. your date means 1976. as that casting number didn`t exist in 66 and was no longer used in 1986.

Good Luck with your 350 Rebuild, that is a Good Block....
70 Nova, you have a Good Block for Rebuild, Like the other post says, your 2-bolt main is Plenty good enough. I love 350 Engine's , they are strong and plenty fast.

Good Luck with your Rebuild, I am also rebuilding a 350, and it is a 4-bolt main block. I did not know it was a 4-bolt main block until my friend brought it to my house.



Good Luck Hot Rodder!

the "010" block, along with it being the high nickel version, is about the best there is for a good buildup. I've got the same exact thing at the machine shop now. Going 30 over, coated Speedpro Hypers, crane cam, so on and so on... LOL
