My 71 Nova SS is a 12A car with the numbers matching block. Casting date of Sept. 12, '70 but a build date of Dec. 2.
GM was on strike Sept. 15, 1970 to Nov. 20, 1970.

I don't know if it applys with these cars and the LT1 but,
my 69 RA IV conv's engine has a similar gap. evidently the RA IV motors were built in batches and it often took months before a car was built with one. I would guess Chevy's high volume might make this theory not apply

I like em both...... at 02's prices
