The 400 small block was used in blazers,pickups and large chevrolet cars. I think it was some where around the late 60's to the mid 70's.

Call'm boats. Big 4 door sedans mostly and stationwagons.
The 400's went into the family sedans, P.U. trucks, Vans (work trucks), Blazers and i think some Laguna Chevelles. No Vettes or Camaros. So most blocks in those cars saw little abuse and may have acceptable cranks for a street warrior. But the work trucks???
I still find them (Chevy 400's) in the pick-a-part boneyards - a few in each yard. torqvette let me know if your looking for a junkyard piece down here in the LA basin - send a PM and i'll see what i can do to help. Ecology only wants $200 for a pull your own - and i think gives a small warrenty too. That's a used 400" sb on my list for my next eng too.
Had a 400 Pontiac in my GTO and a great motor. Back when GM cars had some identity and the different car lines had they're own engineering and engines that gave them appeal instead of the corporate clones - but now look at GM's situation.
Long rods and BB vlvs made 400hp with just a good cam up grade to the mtr - using stock Poncho heads and crank. Spin the tires just by stomping on it at 5mph. Still find a few Ponty 400's, 455's and even a 426 in the boneyards here. Not much work to swap for a Chevy eng as the old Firebird motor mounts allow it. Pontiac used a different bellhousing though. But the 455 Ponty was just a stroked 400 and make some brutal torque. If u want a torque monster vette for the price of a rebuild kit a 455 swap would be fun.
Hope this helps. cardo0
