Yep, 4 inch bore by 3.31 stroke, 333 cubic inch (or 332.75). JE stocks a flat top SRP 4 inch bore piston (P/N SRP 345794S) with a 1.804 compression height for a 318, but they're flat tops. But that could easily be configured as a domed piston. But, it's going into a southeast gasser super stock competitor (1/8 mile) it will be running on 110 octane leaded with as close to 13:1 compression as is possible. And weight requirement is 9-1/2 lbs/cubic inch. So how quick it really can be is mandated by the rest of the competition. I don't know what kind of times they are running in super stock to be competitive (only the racers know their times, only the win lights come on at the finish), but I am suspecting it's in the 7 second range. But if anyone becomes dominant over the rest of the field by more than .15 second for more than one race they receive a "performance limiting plate" to put under the carburetor. So ultimately, that's going to have to be decided by who has a naturally aspirated 318 with a 3.31 inch stroke that shows us a time slip that's comparable or quicker....
