Big block 383 build!

The pist are kb with dome and if they sit .027 in the hole I will still be around 9.3 depending on cc of the 906 heads!I would have zero decked but it was already machined 30 over when i got it and had never been put together.My truck has been down for over 5 yrs and I dont make awhole lot of money but I am gonna build a new 440 after couple of years.Right now i just wanna drive!But it might be zero decked will not know till i put it together!The guy that machined it died so if it is zerodecked it will be over 10 to 1.
