Quote: I was talking to a nhra E/SA 340 6pk racer and he said nhra allows the piston to be .045 out of the hole. I just did a 340 an used L2316 piston w/ a 1.84 cd and they ended up .035 out of the hole. This block has been decked,I'm sure your right about the .018 factory spec. Thanks Ryan
+ .045" is NHRA Blueprint spec on 68-71 340.......not factory specs.
and for this particular engine the chambers would have to be relieved, and so like edelbrock maybe they should offer two heads
