010 blocks are good blocks the engine code in the vin # will tell you the original motor.

Available engines in 1970 Chevrolet Nova's
4 Cylinders 2.5L 1BL OHV

6 Cylinders 4.1L 1BL OHV
8 Cylinders 5.0L 2BL this would be a 307 not a 302...

8 Cylinders 5.7L 4BL OHV
8 Cylinders 6.5L 4BL OHV
8 Cylinders 6.6L 4BL
planning on restoring it????? the only major visible difference between the 350 and a 400 is the harmonic damper and the marks on the ends of the heads... the 400 damper outer ring has a recess.. where the 350 dampers are smooth on the outside..
this may help decoding the vin..
