Hi, i have a 70 454 with this block: 14015445 (1982) and the suffix cod xch..
this is a ls7 crate engine..
for the italian immatricolation i need the original block but if i can demostrate that my block (14015445 xch) is an engine replacement for the corvette i don't have problem..
i found just this, but there isn't my casting number and is not significant i think
thank you for any helps..
