I doubt the 113 cc. chamber. I sell a few of these every year. Most come out about 117 after a modest mill cut.
I sold a pair last week, almost the same, but with 2.19" intakes. Set up for a .620" hyd roller cam, for $550.00 exchange. That was less $$ than the other local shops. But, the customer bought a 496 short block from me earlier in the year..
