Brady,I see a 305 at 14010201. let me look for more.

Thats all I see. 305 80-84 ; 2 bolt main car, truck. The number lettr combo on the front of the block is the best way to ID, a block. The last letters, usually three of um like CKB, or TLK. They are in front of the pass, sice head on the little flat spot on the block. behind the alternator on 70's and up vehicles. You can buy a $12 book that will tell you everything you need to know. At any bookstore. Or swap meet. If not just ask. I'll dig it up..

If your down to the cylinders, 4 inch = 350...3.750 = 305..Go to www.MorTec.com . Look in the back for all Chev. casting #'s..Good to have all the old (and new) casting numbers....Hope this helps..Good Luck
