NEED INFO! 383bb PLEASE

I have the same block as you , it is a 383 cast crank. You can use the crank, but don't go too wild with the build, definitely replace the pistons with aftermarket higher compression, you can get pistons for stock stroke, stock rods and stroke, or 440 rods with stock stroke, or you can do what I did. I used the block, a 440 crank, stock rods, and Diamond stroker pistons, I now have about 432 cu in stroker. If you did the same with a 400 block, you get 446. Or, you can go with 440 Source stroker kit and end up with almost 500 cu in.

Obviously, money talks. If you stay stock with better pistons, about $350, 432 cu in will cost you about $1100, 500 cu in will cost you $2000. Of course, this is just for the rotating assembly, machine work and other rebuild parts will cost you more.
