Need some info on a 393 stroker
 

I am thinking about building a 393 stroker since I need to replace my crank and rods and pistons anyway. WHat is the bore and stroke for a 393? Also will 1 3/4 headers and a 750 holley DP be big enough? Thanks for any input.

3.850 stroke and 4.032 bore. Those headers will be enough and that carb will work.
