Might even be beneficial to get a long block already clearanced and reay to go from somewhere like Summit Racing.

I agree with GASoline71. My block had a moderate core shift and clearancing the block had to be done very carefully. In the end we also spot faced the rods a tiny tiny bit and machined the rod bolt heads down a tiny bit to get the clearance in the bad areas. Every little bit counts! But you need someone who knows what they are doing. We measured everything twice, checked and re-checked the cam timing, bore to piston clearance, bearing clearances etc. It seemed like overkill at the time but the engine fired on the first crank and (knock on wood) has run great for the first 500 miles! I love my 383 and am glad i went that route.
Machining the block and assembling the bottom end is where we spent a lot of time. A long block assembled for a 383 application will save you a lot of time and probably money too! This route still allows you to pick the heads, intake, and other cool stuff.
