No, nearly all 1970 455s are drilled for four bolt mains, but fitted with two bolt caps. Only a few high performance models actually got the four bolt caps from the factory.

Is 9799914 Pontiac a big block?
First things first. There are no "Big or Small" block Pontiac's. They all share a common design and general dimensions from the 265 all the way up to the 455. The exception is the 265 and 301, which are short deck. 350-400 cu. inch. engines have a 3.00" main where the 421-455 engines have a 3.25" main. On to your block. The 9799914 is was a 400 cubic inch block that was cast in 1970. The 1970 Ram Air III used this block with 4-bolt main caps. Everything else got the block without the 4-bolt main caps, but were drilled for them. Your application code stamped on the right front of the block near the timing cover will narrow it down for you. Hope this helps. Britt Bettell
