Looks like a VERY clean one to start with!

Is that a Y4 Gold RR????

Personally, date codes and casting dates are a romanticized element when it comes to a non-original matching #'s set-up.

My 383 based 69 RR will get any year 440 that is best suited to build as big of HP as my budget will allow at the time of build. I'd almost prefer to sell the 68-72 era 440 blocks I have now to buy stroker kits but it hasn't come down to that yet.

Post more pic's as you progress...........
