stopped in to see a local guy today who has quite a well deserved reputation as a top notch engine builder [ most forum guys around here know dean ireland ]. i wanted to talk to him about building a stroker 383, he said, well doug, have you considered a 406 ? long story short - he has a 1970 four bolt 400 block and brand new rotating assembly for it with forged crank and rods. hmmm.....will have to put some thought into this one !!!
