The 854 block In 1970 was a 402. So it's .30 over. The pistons say .60 because they're l78 pistons for a 396. So I guess you could say it's a .60 over 396 but that wouldn't be fully right because it never was a 396, like I said 402 from the factory. The pistons are gm TRW pistons too if anyone wants to know.
Thanks
