Not in my car,I built it because everyone said it could not be done and make any HP.I sold it BUT just built a 383 301 RA V engine but we had a issue with the custom made hybrid head gaskets.It is now being rebuild with the Butler gaskets like i used in the first build.A little less cam,not sure if it will make the HP of the SD ported Dports.It will go in my 69 firebird.The shop is starting to put it back together next week.The head gaskets would not hold water.We will pressure test it this time!Tom
