Here you go,
3855961....396.......65-66...2 or 4 bolt
3855961....427.......66......2-bolt
3856206....65-66...oval..CLOSED..396, 97cc chamber
Great block & lrg oval port heads with small chambers for good comp ,makes a great street perf motor but be advised it requires a grooved rear cam bearing and also a cam that has a groove in the last cam journal all for oiing the lifters.
Some of these 396 blocks can be safely bored to 427 because GM used the same 961 blocks for 427 bbc from the factory in 65 & 66 but to be safe i would have the block sonic tested before doing so .
